Selective Remote Sensing Image Fusion Method Based on the Local Feature of Contourlet Coefficients
Zhu Kang, and He Xinguang
In order to remarkably improve the spatial resolution of the fused multispectral images and preserve the original multispectral characteristics as much as possible, a selective remote sensing image fusion method is proposed based on the local feature of contourlet coefficients. Firstly, a window neighborhood mobile tem

Influence of Dynamic Focusing Conditions on Bone Hard Tissue Ablation with Pulsed CO2 Laser
Liu Haishan, Zhang Xianzeng, Zhan Zhenlin, Zhao Haibin, and Xie Shusen
Defocusing phenomenon induced by the change of the work distance in the irradiating process of biological tissue has an important influence on the effect of hard tissue ablation with pulsed lasers. Fresh bovine shank bone in vitro used in the experiment is put on a computer-controlled motorized linear drive stage and i

Photoacoustic Imaging of Human Thyroid Based on Long-Focal-Zone Focused Transducers with Different Frequencies
Zeng Zhiping, Xie Wenming, Li Li, Li Zhifang, Li Hui, and Chen Shuqiang
There exist misdiagnosis and missed diagnosis with routine ultrasound imaging of thyroid nodules in present clinic. A novel method employing a series of long-focal-zone focused transducers with different frequencies for photoacoustic imaging (PAI) is presented. Some blood clots in different sizes are embedded in tissue

Elliptical Hermite-Gaussian Spatial Optical Soliton and Phase Shift
Wang Qing, Wang Xinghua, Xie Yingmao, Luo Xinglong, and Li Dongbo
The propagation properties of elliptical Hermite-Gaussian light beam in a strongly nonlocal nonlinear medium are studied. As the characteristic width of response function of strongly nonlocal media is much bigger than the beam width, the response function is expanded twice with Taylor series and the series are both pre

Progress in Photobiomodulation Studies
Liu Chengyi, Cai Qing, Karu Tiina I, Duan Rui, and Wilden Lutz
Photobiomodulation (PBM) is a biomodulation of laser irradiation (LI) or monochromatic light. The LI may be low intensity LI (LIL) at about 10 mW/cm2, moderate intensity LI (MIL) at 0.1~1.0 W/cm2 or high intensity LI. The progress in PBM studies is reviewed from homeostatic viewpoint in this paper. Function-specific ho

Studies on Tm-Doped Double-Clad Fiber Lasers
Du Geguo, Zhao Junqing, Zhang Lingcong, Guo Chunyu, Yan Peiguang, and Ruan shuangchen
Tm-doped fiber lasers have a huge applied prospect because of their emitting wavelength about 2 μm in the absorption of water molecules, eye safety and being considered to be effective pump sources for 3~5 μm optical parametric oscillator. This paper launches a series of studies on continuous wave laser, pulsed laser a
