Investigation on Mirror Reflectance, Grating Efficiency and Film Optical constant at VUV Spectral Range
Abstract：VU-V reflectometer and poIarizer have been developed and VUV measurement equipment for mirror reflectance and grating efficiency has been established, VUV mirror reflectance for four kinds of samples such as Al,Al+mgF2,Au,Pt made under dif f erent technology condition and grating efficiency were measured at this equipment, By means of computer best fitting technique film optical constant was evaluated from the reflectance and the polarizition degree and compared with the data publfished abroad.- 57

A Computer-controlled CCD Image Display System for the Dpticaf Processor of a Synthetic Aperture Rader
Abstract：This paper discribes a computer-controlled CCD image display system with high resolution, which has been develaped for checking the imaging effeciency and quality of the datum negative in the optical pracessor of a synthetic aperture radar.The hardware interface circuits for quickly transiering data and the design of assemlaly language programs are also introduced.With the specific high resolution colour graph-controlled circuit board the resolution of the system can be up to 1k×1k×8bits, hence it is very canvenient to adjust and test.The system is stable and relialale in properties and abundant in colaurs.The pseudo-colour real-time rolling display provides convenient conditions for digital image prosessing.- 37
