像增强型夜视系统的图像信息传递

在分析了像增强夜视系统信息传递的基础上，指出像增强器输出端荧光屏至人眼的图像传递过程，构成了像增强夜视系统信息传递量的限制．提出了采用系统信息传递量作为夜视系统设计与评价的方法，利用这种方法可以发现在像增强器增益足以补偿光谱选道衰减的条件下，采用彩色像增强可以大幅度增加夜视系统传输的信息量．

IMAGE INFORMATION TRANSFER OF IMAGE INTENSIFIED NIGHT VISION SYSTEM

Based upon the analysis of information transfer of a typical image intensification system, this paper shows that the image transfer from the output screen of the intensifier to the eye makes up limitation to the whole system information amount, and proposes that the use of color image intensification when utilizing the transfor of information as the means of design and evaluation of night vision system, under the condition that the gain redundancy of image intensifier can compensate spectral gate attenuation, will realize larger information amount than the conventional image intensification.
