Abstract
Image-intensification has been improved constantly by enhancing the gains of image-intensification more and more, to achieve more sensitive imaging at low light-level. When the sensitivity needs for night vision have been satisfied, further improvement should be the enhancement of night vision image information quantity. On the basis of analysis of information transfer of an image-intensification system, this paper shows that the image transfer from the output screen of the intensifier to eye makes up limitation to the whole system information quantity, and proposes that color image-intensification utilizing spectral gate and color assignment, in the case of that the gain redundancy of image intensifier can compensate adequately spectral gate attenuation, will realize larger information quantity than conventional image-intensification. Then, give out a color image-intensifier scheme combining time-shared photocathode and spatial multiplexed screen.
