相对照度的优化,急!

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 |
Excuse me, the definition of two functions ^output(*,*) ^pol_input(*)
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.
在这个例子之前还要运行命令:
in ill

[B]以下是引用[I]redflag[/I]在2005-7-13 10:19:17的发言:[/B][BR]You can use the simple formula define as blow:
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%
