HU Gu-Jin, ZHANG Ting, SUN Jing-Lan, ZHU Da-Ming, CHU Jun-Hao, and DAI Ning
Dielectric behavior of PbZr 0.38 Ti 0.62 O 3 multilayer with alternating dense and porous PbZr 0.38 Ti 0.62 O 3 layers was investigated at 420K. Two distinct dielectric relaxation processes were observed in the frequency range from 102 Hz to 10 6 Hz. The relaxation at lower frequencies is attributed to the space chargeDielectric behavior of PbZr 0.38 Ti 0.62 O 3 multilayer with alternating dense and porous PbZr 0.38 Ti 0.62 O 3 layers was investigated at 420K. Two distinct dielectric relaxation processes were observed in the frequency range from 102 Hz to 10 6 Hz. The relaxation at lower frequencies is attributed to the space charge polarization. The one at higher frequencies, with a thermal activation energy of 0.49 eV, might originate from the response of singly positive charged defect dipoles V ¨ 0 -Ti 3+ to ac electric fields. These dipoles are formed by the doubly ionized oxygen vacancies V 0 and trivalent titanium ions Ti 3+ as indicated by the results of Auger electron spectrum and electron paramagnetic resonance spectrum..

Te-rich dipping technique of HgCdTe liquid phase epitaxy (LPE) was studied. An experimental method was proposed to check the homogenization of (Hg 1-x Cd x ) 1-y Te y melt just before the dipping. The gas convection and Hg cir- cumfluence in the growth chamber were suppressed by reducing the free space of gowth chamberTe-rich dipping technique of HgCdTe liquid phase epitaxy (LPE) was studied. An experimental method was proposed to check the homogenization of (Hg 1-x Cd x ) 1-y Te y melt just before the dipping. The gas convection and Hg cir- cumfluence in the growth chamber were suppressed by reducing the free space of gowth chamber. The process control of the growth temperature was improved to suit for the poor temperature reproducibility induced by the gas convection and Hg cir- cumfluence. In this way, the composition reproducibility of MW HgCdTe grown by LPE reaches ±0.005. The thickness uncertainty is controlled to be within ±5μm and the transverse composition uniformity (standard square deviation/average) for 40×30mm 2 wafer is less than 1.3×10 -3 . The differences of the composition and thickness are less than 0.001 and 1μm, respectively, for the different wafers grown at the same time. The surface fluctuation of the sample is less than 1μm for over 10 mm dimension. It was also observed that, after thermal treatment, our p-type MW HgCdTe epilayers with Hg- vacancy doping have higher hole mobility at 77K compared with the materials grown by other techniques. Besides, com- pared with horizontal slide LPE, the dipping technique has obvious advantage in the manufacture of large size HgCdTe films and multi-wafers with the same property. Hence, the technique is helpful to develope the batch manufacturing technology of the second generation HgCdTe infrared focal plane array, and it is also significant to develope the splicing of super-large- scale infrared focal plane arrays..

COMPARISON OF INFRARED 11μm WINDOW CHANNELS FOR MEDIUM RESOLUTION SPECTRAL IMAGER AND VISIBLE AND INFRARED RADIOMETER ON FY-3 METEOROLOGY SATELLITE
BI Yan-Meng, YANG Zhong-Dong, LU Qi-Feng, and ZHENG Zhao-Jun
The different remote sensors on China new generation meteorology satellite FY-3 have similar thermal infrared channels.

For the visible and infrared radiometer (VIRR) infrared 4-channel and medium resolution spectral imager(MER- SI) infrared 5-channel, the line-by-line radiative transfer model (LBLRTM), in which the atmospheric profiles adopt glob- al 52 atmospheric profiles generated by ECMWF, was performed to calculate the spectral radiance emitted from the earth-at- mosphere between 8μm and 14μm. The radiance received by the satellite was computed combined with the spectral re- sponse functions of channels and then the theoretical relationship of the brightness temperatures for the two channels was an- alyzed. The FY-3 actual observation data at QingHai Lake in September 2008 was used to examine the relationship. The comparison of the results indicates that the brightness temperatures for both channels calculated by LBLRTM agree each other well, but the temperature obtained from MERSI is lower than that from VIRR. The temperature difference between the two channels increases with the increase of temperature. Because FY-3 actual observations are affected by many factors, VIRR temperature is lower than MERSI, which is different from the theoretical result of the model. The matched MODIS data is used to compare with MERSI and VIRR. It is concluded that VIRR might underestimate the temperature. The deviation of MODIS and MERSI temperaturesis within the absolute accuracy of the temperature measurements. The results described here should be valuable for assessing the similarities and differences for the two similar infrared channels of MERSI and VIRR..

Simulation results show that the absolute evaluation error of the system MTF at half normalized spatial frequency is about 0.05 for an ordinary system with good performance. Meanwhile, the system MTF characteristics of FY-2C satellite thermal infrared band (IR1) were quantitatively evaluated with observed data from 2006 to 2008, which is consistent with those measured by on ground testing. By using the derived system point spread function(PSF), the images of FY-2C IR1 were recovered with more detailed textures. It improves the monitoring performance for some typical typhoon. The ideal step-profile model used in the traditional on-orbit MTF evaluation can be regarded as a special case of the proposed ideal slope-profile one where the parameter N slope equals zero. Therefore, the proposed method is also suitable for on-orbit MTF evaluation of visible and near-infrared bands..

Hyperspectral reflectances of the healthy and lodged rice caused by rice planthopper and rice panicle blast were measured with visible/near-infrared (VIS/NIR) spectroradiometer at the canopy level.

The principal component analysis (PCA) was used to obtain the principal components (PCs) and to reduce the spectral dimensions of hyperspectral reflec- tance. Two principal components were extracted. The first (PC1) and second (PC2) reveal the general feature of rice spectral reflectance and spectra change of lodged rice relative to healthy rice, respectively. The front two PCs entered the support vector classification (SVC) as the input vectors to build the discrimination model. The recognition accuracies of healthy and lodged rice are 100% and 90.9% for the rice planthopper and rice panicle blast stresses, respectively. The results demonstrate that visible/near-infrared spectroscopy technique may provide potential discrimination accuracy for lodged rice..

WANG Feng, ZHOU Yi, YAN Fu-Li, YANG Shuo, and DU Cong
An atmospheric correction algorithm based on zero water leaving reflectance in short wave infrared (SWIR) bands for case Ⅱ waters was presented. It used two SWIR bands of MODIS(1.240μm and 1.640μm) to extrapolate the aerosol scattering reflectances of visible and near infrared ( NIR ) bands.

It used two SWIR bands of MODIS(1.240μm and 1.640μm) to extrapolate the aerosol scattering reflectances of visible and near infrared ( NIR ) bands. Then water leaving reflectances in visible and NIR bands could be retrieved. This algorithm was tested over coastal waters and lakes in the east part of China. The correc- tion results were compared with both in situ measurement data and those by other atmospheric correction algorithms. The results show that the algorithm removes the effects of atmosphere effectively..

The amplitude and phase distributions of the electric fields at the specific distance from the optimized co-aperture object simulator were computed by using the commercial EM software. The numerical results illustrate that the phase variation of the electric fields of the co-aperture object simulator is very small after optimization, and good direction consistency of infrared and millimeter-wave signals is also observed..

Five different varieties of rice bought from the supermarket were identified with visual/near infrared spectroscopy (NIRS) technology.

The spectra were collected by using ASD FieldSpec . 3 spectrometer, and 35 samples were obtained for each variety of rice. All the samples were divided randomly into two groups, one group with 150 ones used as calibrated set, and the other with 25 ones as validated set. Then the samples were analyzed with the whole wave band and the charac- teristic wave band(400～500nm, 910～1400nm and 1940～2300nm) models, respectively. The samples data were pre- treated by the methods of S.Golay smoothing and standard normal variable (SNV), and then the pretreated spectra data were analyzed with principal component analysis (PCA). The anterior 9 principal components computed by PCA were used as the input variables of back-propagation artificial neural network (BP-ANN) which included one hidden layer, while the values of rice varieties were used as the output variables of BP-ANN, and then the three layers BP-ANN discrimination model was built. The 25 unknown samples in the validated set were predicted by ANN-BP model. The results show that the discriminating rates are 100% in both models, and the accuracy of characteristic wave band model is higher than that of the whole wave band model. The results indicate that it is feasible to discriminate the variety and authenticity of rice by visible/ near infrared reflectance spectra as a rapid and non-contact way, and selecting characteristic wave band is one of the valida- ted methods to improve the precision of the discrimination model..

In order to simplify PLS model, net analyte preprocessing (NAP) algorithm was used to extract some useful net analyte signals from the raw spectra, then three NAP/PLS models of EGCG, ECG and EGC were constructed. The number of NAP factors and the number of PLS components were optimized by cross-validation. The spectral preprocessing result of NAP algorithm was compared with that of the classical standard normal variate(SNV). The predicting result of NAP is almost similar to that of SNV, but the number of PLS components factor by NAP is much less than that by SNV. This work demonstrates that NAP pretreatment can simplify the prediction models of catechin content in green tea..

PIAN Zhao-Yu, and MENG Xiang-Ping
A biological visual based contour detection model was presented. Firstly, the response function of single visual cell was simulated by researching on the structure of primary visual cortex. Then, a new neighboring effect term was constructed to characterize the neighboring interactions of the neurons in receptive fieldA biological visual based contour detection model was presented. Firstly, the response function of single visual cell was simulated by researching on the structure of primary visual cortex. Then, a new neighboring effect term was constructed to characterize the neighboring interactions of the neurons in receptive field. By considering the difference in distance, posi- tion and preferred orientation between neighboring stimuli and the central neuron, the model effectively suppresses the inter- ference of the background texture and enhances the response of the neurons with the same configuration. Thus, it obtains a clear contour. The experimental results show that our model overcomes the drawbacks of the traditional algorithms, and it has a better detection accuracy and stability, and it can obtain the gratifying results in actual detection mission..

ZHU Da-Zhou, JI Bao-Ping, SHI Bo-Lin, PAN Li-Gang, TU Zhen-Hua, MENG Chao-Ying, and QING Zhao-Shen
The transmittance/reflectance NIR spectra of fresh apple juice were collected by immersed fiber at four optical path of 5mm, 10mm, 15mm, and 20mm. The NIR spectra were used to predict quantitatively the soluble solid contents (SSC) and pH value of apple juice. The results show that the optimal optical path lengths for The transmittance/reflectance NIR spectra of fresh apple juice were collected by immersed fiber at four optical path of 5mm, 10mm, 15mm, and 20mm. The NIR spectra were used to predict quantitatively the soluble solid contents (SSC) and pH value of apple juice. The results show that the optimal optical path lengths for SSC and pH are different, which are 5mm and 20mm, respectively. In order to consider the concentration ranges of different components and their op- timal path lengths, multi-optical path spectra were used to construct the model to improve the model quality. The method for extracting information from multi-optical-path spectra was studied. The method based on directly unfolded spectra could effectively use the spectral information, but the model became more complex and the calculation time was very long. Two methods based on wavelet transformation were proposed to extract the information. They can extract the multi-optical path spectra information effectively, and at the same time the calculation time decreases significantly and the model is simpli- fied. One of the methods that uses the approximate wavelet coefficient of the unfolded spectra to construct model has the best performance: SECV for SSC and pH value are 0.4761° Brix and 0.0779, respectively..

Analy- sis of a large set of data confirms that the data abnormality is mainly due to the influence of clamping (zero-voltage fluctua- tion) on each waveband. Thus, a method based on clear water free network adjustment was put forward for repairing the clamping. Then, the clamping repair method was applied to the remote sensing image and the chlorophyll concentration was retrieved from the clamping repaired image. The retrieved products have excellent uniformity and abundant detail. Finally, the comparison between the retrieved and MODIS/Aqua products demonstrates that the clamping repaired signal is right. It provides a new method for the clamping repair and a support for the quantitative application of ocean color sensor..

Backward interval partial least squares (BiPLS) and synergy interval partial least squares (SiPLS) were pro- posed to search for an optimized combination of information spectral intervals about soluble solids content (SSC) from Vis/ NIR spectra of peach. A linear combination weight PLS model was developed on the basis Backward interval partial least squares (BiPLS) and synergy interval partial least squares (SiPLS) were pro- posed to search for an optimized combination of information spectral intervals about soluble solids content (SSC) from Vis/ NIR spectra of peach. A linear combination weight PLS model was developed on the basis of the selected information inter- vals. The spectra were preprocessed by second-order derivative and Savitzky-Golay smoothing. It is found that the selected result is the best when the interval number is 15. The information intervals selected by BiPLS are 742～770nm and 862～ 920nm, while those selected by SiPLS are 742～770nm, 832～860nm and 892～920nm. For BiPLS and SiPLS models of direct combination intervals, the root mean square error of prediction (RMSEP) are 0.386 and 0.308, respectively. And for the PLS models of linear combination weight, the RMSEP are 0.351 and 0.364, respectively. The results reveal that the proposed method overcomes the difficulties that the different information intervals for the complicated samples have dif- ferent contribution to PLS models. The metlod is very promising for vibrational spectroscopy and it gives much better predic- tion than the whole-spectrum PLS modeling..

By cal- culating the neighborhood homogeneity measurement (NHM), the transform coefficients can be fused local adaptively. Ex- perimental results demonstrate that the proposed approach outperforms the traditional methods which are based on wavelet transform and contourlet transform in terms of visual quality and quantitative criterion..

However, Wedgelet, which is a multiscale geometric analysis tool, has an advantage of catching linear features. Aiming at further reducing speckle noise in SAR images, a modified cost function of Wedgelet transform was proposed. Besides, proper transform scales were selected in order to highly improve the transform speed without affecting the quality of the approximation. Based on the improved Wedgelet transform, edge detection was preformed. Experimental results show that the proposed method can suppress speckle noise in SAR images successfully and extract edges from SAR images effectively..
