相对照度的优化，急！
<P><FONT size=3>小弟目前正在进行手机镜头的设计，周边相对照度很低。<FONT face="Times New Roman">CODE V</FONT>好像无专门对相对照度进行优化的指令，各位先进能帮小弟解决这个问题？谢谢。</FONT></P>

没有吧，自己要去寻找能够减轻cos四次方因子的原始结构。优化后时刻观察计算注意边缘视场的相对照度。

<P>Hi</P><P>Above method would still be not correct if you have vigneting or if the shape of the light awl on the cross surface is not close to ellipse.</P><P>If someone could write a macro tracing a bound of ray and calculating the solid angle, that would be more correct. </P>

<b><FONT size=2>…这个宏执行起来似乎有问题！能否再请您确认一下，谢谢。</FONT></b>

在这个例子之前还要运行命令:
