The developing technology of imaging detection needs more higher resolution of optical systems. According to the traditional optical theory, the aperture should be enlarged to fit the reqllirement. Bait it is difficult to achieve this method in such a system with limltod scale, weight and Price. A pupil super-resolution technique based on the Rayleigh Criterion as a PIV index is studied and presented in this paper. This method can improve the system resolution without the enlargment of aperture of optical system. There super-resolution pupils have been designed based on the theory analysis, and the results of computer simulations are also presented here..

A New Method for Measuring PMT Spectral Characteristic
[in Chinese], [in Chinese], [in Chinese], and [in Chinese]
A new method for measuring spectral characteristic of photo- electron multiplicate tubes (PMT) is proposed. The basic idea is to utilize an acousto-optic filter as the dispersing element. The system was calibrated by using time delay technique, so that monitoring beam can tube from measuring beam directly.

In this paper,we have obtained LIF spectrum of D1 ∏→ X1 ∑+ of NaK induced by 514. 5 um of CW Al+ laser, assigned the spectrum by the known molecular constants, analysed and discussed the emission mechanism of LIF in detail. The vibrational constants of X 1 ∑+ state have been provided by using the least-square fit. The calculated wavelength values are in good agreement with the measured results. We also calculateFranck- Condon factors and intensities of each Q-branch transition. The computed intensities coincide with the observed very well in considering dependence of transition dipole moment Re(r) on r. It proves that the values of vibrational and rotational quantum numbers (v,J) we have determined are reasonable..

Optical absorption spectra and optical constants of the vacuum sublimed films of copper phthalocyanine (CuPc) were studied. A comparatively strong absorption was oberved at wavelength region of 550 to 750 nm. The static optical recording test of a CuPc film indicated that low power He-Ne laser irradiation could produce a relatively large reflectivity change. The introduction of metallic reflective layer on the recording layer will raise the writing threshold energies and maximize the reflectivity contrast..
