摘　　要：针对目前微观夜视仪器产生单色图像的缺陷,提出了一种单通道三波段的彩色夜视方案。简要介绍了单通道三波段彩色夜视系统的工作原理,重点论述了该系统的设计方法,并对滤光片的光谱透过率、色轮的窗口数量、荧光屏与CCD光电阴极的耦合方式等问题进行了计算和分析。在单通道三波段彩色夜视系统装置研制基础上,开展了彩色夜视实验,成功得到色彩较为真实的夜视图像。Low-light level night vision device produces black and white images, which isn＇t conducive to long time observation of human eyes. To solve this disadvantage, a night vision system of single-channel triple-spectrum is put forward. Working principle of the color night system is introduced briefly And the design method of the system is discussed. The spectral transmittance of filters, the number of color wheel windows, the coupling modes of fluorescent screen with CCD and other questions are calculated and analyzed. Color night vision experiment is done by color night vision system of single-channel triple-spectrum. The result shows that the system designed could produce color night image preferablly.
