如何在ASAP中计算PST

asdoptics

和昨天的自动计算不同，本文提供一种常规的方法来计算PST，步骤如下：

1.Defininga collimated grid of rays at the entrance tothe system

2.Normalizethe power of the grid to obtain unit irradiance

PI=3.1416

GRID ELL Z -20 -4@6 25 25

SOURCE DIRECTION 0 SIN[40] COS[40]

FLUX TOTAL PI*6^2*COS[40]

3.Traceand scatter the rays to the detector

4.UseSTATS  to find the stray light power onthe detector

5.Dividedetector power by detector area to obtain PST
