| 摘 要： | 光密度是激光防护镜最主要的一个质量指标,这一参数的测量在原理上是简单明了的,但是当光密度大于3时实践上有许多困难,本文介绍一种用激光源、双光路分束的光密度测量装置,结合计算机采样处理,光密度测量范围可达6.

| Abstract: | Optical density D ,defined as D =-log(transition light power P t/total incident light power P i),is one of important performance figures of laser eye protective glasses.In practice,it is defficult to make the measurement of parameter D >3.This paper proposed a measurement system including a laser source,double optical path subsystem,a data sampling and processing subsystem with computer.With the system,the case of parameter D >6 can be measured. |
