介绍了一种在天基空间监视相机中应用的新型的自动调光系统,该系统是由单片机控制,采用AD536真有效值检测专用芯片作为CCD相机视频信号的检测电路,并采取程序控制方式对天基空间监视相机系统进行自动调光控制的设计。
This paper introduces a new type of automatic dimming system used in space-based space-based camera. The system is controlled by a single-chip microcomputer. It uses AD536 true-rms detection chip as the detection circuit of CCD camera video signal and adopts the program control method Space-based space surveillance camera system for automatic dimming control design.
