主动夜视是在黑暗甚至无光的情况下，完成对目标监视的一种手段，是夜视技术的一个重要分支。本文介绍了近红外主动夜视的照明光源，从研究主动夜视的特点入手，分析光源的几种共同特性，研究几种不同的光源。对设计、使用夜视光源，提出了有益的参考。 Active night vision is a means to complete surveillance of the target in the dark or even no light, and is an important branch of night vision technology. This paper introduces the illumination source of near-infrared active night vision. Starting from the study of the characteristics of active night vision, analyzing several common characteristics of light source and studying several different light sources. On the design, the use of night vision light source, made a useful reference.
