This paper introduces the development study of Reflector board(cooperative target) reflectivity measuring instrument.
本文介绍了反光板（合作目标）反射率测量仪的研制。
The system is composed of off-axle paraboloid reflector, cross line target, background light, imaging collecting system and other devices.
该装置由离轴抛物面反射镜、十字靶标、背景光源、图像采集装置及其它附件组成。
The results illustrate that through the role of reflector cup on the LED, we can get a uniform rectangular facula in the target surface.
在光学软件中对反射器光学系统进行照明模拟，结果说明通过自由曲面反射器作用于LED，可以在目标路面上形成均匀照明的矩形光斑。
