摘要:
基于DSP+FPGA架构,采用全透式光学系统及非制冷红外探测器和CMOS探测器,设计并实现了一种轻小型双谱段相机。该相机同时具备红外和可见光成像能力,可作为小行星探测用光学敏感器的原型机,也可作为微小卫星的光学载荷。首先,建立了双谱段相机的技术指标体系;其次,论述了相机的组成和基本工作原理;再次,详细阐述了相机的光学系统和电子学设计;最后,介绍了原理样机的研制情况。

Abstract:
Based on DSP+FPGA configuration, a small and light-weight double spectrum camera is designed by adopting absolute perspective optics system, uncooled infrared sensor and CMOS sensor. It images both by infrared and visible light, can be used as prototype of optics sensor for asteroid detecting. It also can be used as optics payload of small satellites. This paper sets up the technique index system of double spectrum camera, discusses its components and working principle, expatiates its optics system and electronic design, and introduces the research overview of the prototype.
