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。

aut;

@RI == (M F2 R2 SI) - (M F2 R3 SI)*(L F2 R4 SI)/(2*(M F1 R2 SI)**2) @RI 0.60 ！！第二视场F2的相对亮度大于60%

save above txt as one ill.seq

below is the usage sample:

dro fct @ill	! delete this fct if it exist
res cv_lens:triplet	! sample
in ILL	！ load above macro fct
lvr	! list the var
aut
efl = 100
@ill(1,2,0,20) = 0.5	! field at 20 degree 's relative illumination is 0.5
wtc 1
dra sa
go

wri @ill(Zoomk,wave,X direction field ,Y direction field) ! curent value confirm

<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>

要想执行没有问题,建议你读一下关于宏的说明.

Excuse me, the definition of two functions ^output(*,*) ^pol_input(*)

redflag

FCT @ill(num ^z,num ^w,num ^x,num ^y)

lcl num ^z ^w ^x ^y ^test ^lum lcl num ^output(10,10) ^pol_input(5) ^pol_input(1)==0 ^axis==tra_1fld(^z,0,0,20,0,1,^pol_input,^output) ^lum_axis==^output(4,^w)

^pol_input(1)==0 ^off==tra_1fld(^z,^x,^y,20,0,1,^pol_input,^output)

^lum_off==^output(4,^w)

^rel_ill==^lum_off/^lum_axis

END FCT ^rel_ill

将上面的文字拷贝后,在CODEV 命令行输入:

edit ill

出现CVEDITOR的窗口后,将其粘贴上去.保存.

再执行 in ill

就可以在优化过程中调用此函数了.

验证此函数:在命令窗口中输入:

write @ill(1,1,0,2.6)

其中的参数的意义为:

1.ZOOM 位置,没有多重结构的输入 1

2.要计算相对亮度的波长,

3.X视场,不是第几视场,用视场实际值.

4.Y视场,同上.

如果你还是不能用的话,就说明你的宏不了解.

建议你多读一些CODEV关于宏的说明. 我讲的已经很详细了.

这是例子. 在这个例子之前还要运行命令: in ill
