围绕如何获得高质量远距离夜间视觉信息展开研究, 介绍一种基于红外短波成像与激光照明的视觉系统, 包括基于 FPGA与 USB的图像数据采集与传输模块以及基于多波段激光照明系统的设计, 展现了较之与传统的视觉系统更远更清晰的视觉图像效果, 讨论了夜间视觉信息的获取距离与照明光源的关系问题。该系统在夜间远距离情况下效果尤为显著, 为海上监视、单兵装备提供良好视野。

This study focuses on the method for obtaining high-quality long-range night-vision information by introducing a visual system based on infrared shortwave imaging with laser illumination, which includes image data acquisition and transmission module based on FPGA and USB as well as the design based on a multiband laser lighting system. It is shown that the visual system is much farther and clearer than the traditional vision system of the visual image. And the relationship between the acquisition distance of nighttime visual information and the illumination light source is discussed. This system is particularly effective in the case of long-distance night vision and exhibits satisfactory performance in the domains of maritime surveillance and man-to-man combat.
