玻璃微珠原向反射屏发散角测试
Test of the divergence angle of a glass bead Scotchlite retroreflector
摘要
Abstract
To test the divergence angle of a glass bead Scotchlite retroreflector, after utilizing a CMOS high-speed camera to take photos of laser spots imaged on a piece of parchment paper reflected by the glass bead Scotchlite retroreflector, the images of laser spots were processed and the divergence angle was calculated according to a certain geometric proportion. The divergence range of the retroreflector was 0. 907° ~0. 956°. Results show that the test method is reasonable and has certain practical value.关键词
