| 摘 要： | 提出了玻璃微珠原向反射屏的剩余发散角概念和测试方法：将激光光束投射到原向反射屏，其反射回的激光光束成像到硫酸纸（接收屏）上。利用相机拍摄不同距离下原向反射屏的成像光斑，得到光斑的图像数据；并处理相应图像数据，计算出剩余发散角。通过实验测得所用的玻璃微珠原向反射屏的剩余发散角为0.447 8°。

| Abstract: | This paper proposed the concept of the remained divergence angle of Scotchlite retroreflector,and designed the testing system.The laser beam was transmitted to the Scotchlite retroreflector,the reflected laser beam was imaged on the sulfuric acid paper(equivalent to receiving screen),and the image data of the laser spots at different distances were captured by using a camera.In order to calculate the remained divergence angle,a program for corresponding image data was written.Experiment results showed that ... |
