摘要
为了测试玻璃微珠原向反射屏发散特性,建立数学模型得到发散角计算表达式,并使用ZEMAX进行光学仿真,并搭建系统测试。使用互补金属氧化物半导体(CMOS)相机拍摄点激光照射在40 cm处激光光斑与经原向反射屏反射后20 cm处发散光斑尺寸,处理两个光斑图像并根据数学模型计算得到原向反射屏的发散角,其发散角为0. 598°。实验结果证明:该方法合理有效,对原向反射屏的特性研究具有一定的实用价值。
In order to test the divergence characteristics of glass bead retroreflective screen,a mathematical model is built and simulated using ZEMAX,test system is set up.The system uses a complementary metal oxide semiconductor(CMOS)high-speed camera to shoot the laser spot at 40 cm and the divergence spot size at 20 cm after being reflected by the retroreflector.The two spot images are processed and the divergence angle of the retroreflector is calculated according to the mathematical model,the divergence angle is 0.598°.The experimental result proves that the method is reasonable and effective,and has certain practical value for the study on the characteristics of the retroreflective screen.
