光圈性能测试系统的总体设计

The Master Design of a Test System for Aperture Performance

系统解决了设定指定光强,以及光强连续变化、目标景像高照度模拟、目标图像高分辨率采集等问题。介绍了光圈性能测试控制系统的硬件组成和功能及软件的结构,对电气控制部分和光学耦合系统的设计进行了详细的讨论。该装置已经通过用户验收,实践表明:各项性能指标均符合要求,使用效果良好且性能稳定可靠。

The test system should be able to set the light intensity to a fixed value, to tune the light intensity continously, to simulate the object image＇s high illumination and to obtain the object＇s images with high frequency. The functions, the hardware structure and the software structure of the test system for aperture performance are presented in this paper, and the designs of electric controller and optics coupling system are discussed in detail. The device has already been checked and accepted by its clients. It is shown that all performance specifications can meet clients＇ need,in a stable and reliable way and good results are obtained.
