[求助]请教：Tracepro中照度图选项中选择归一化和不选择归一化选项有什么区别？ [复制链接]

在Tracepro的照度图选项中有一项“Normalize to emitted flux”，选择和不选择的情况出来的照度图有什么区别？哪位能详细解答一下。 g;[t1

说明书：规范从所有发光源发出的所有出射通量给图的数据，这个选项允许你使通量和光照规范为总共的通量，如果这个框被选中后，TracePro在光照度图中使用出色通量来除以总通量。这对于在光学系统计算的系统透射率和照明系统中计算发光效率，会非常有用。 G^VOA4  
也就是说，比如你的总光源有10lm，得出的照度图在没有选择norm～选项的时候是显示正常的照度，在勾选了之后显示的照度值是原来的/总流明，可以认为是没流明所产生的照度值

谢谢版主的耐心解答，^_^

哈哈

有中文说明书么？可以共享一下么？

Normalize KQw>6)  
Normalize the map data to the total emitted flux from all sources. R>;&4Sjr  
This option allows you to have the flux and irradiance normalized to the total g4+Hq *  
emitted flux. When this box is checked, TracePro divides the values in the V U5</si+  
irradiance map and the total flux by the emitted flux. This is especially useful for J}#2Wy^{  
calculating system transmittance for an optical system, or lighting efficiency for a # kNp);  
lighting calculation. r{SDJa  
Example 1: System Transmittance =]pEvj9o  
Suppose you need to calculate the system transmittance of an optical system. &o1k_!25  
You would probably use the grid raytrace option, and the emitted flux is equal to d'3"A"9R7-  
the sum of the flux in all the emitted rays. When you display an irradiance map, Acd@BL*  
the system transmittance is equal to the total flux, displayed at the bottom of the e+VE FWz
 
irradiance map window, divided by the emitted flux. To get the system p1HbD`ST  
transmittance, check the Normalize to emitted flux box and press the Apply m@w469&<(q  
button. The map will be redisplayed, and the Normalized Flux value will be equal qcQq.cS_'N  
to the system transmittance. ];b+f@  
Example 2: Lighting Efficiency $MfRw
  
Suppose you need to calculate the lighting efficiency of a luminaire in illuminating KMQPA>w#  
a plane. You would probably choose the Surface Source raytrace option, and the T-/3 A%v  
emitted flux is equal to the flux you specified when you defined the sources. When u!F\`Gfm_  
you display an irradiance map, the total flux incident on the observation plane is bz~aj}"`  
displayed at the bottom of the window. The lighting efficiency is equal to the total lB_X mI1t  
flux divided by the emitted flux. To get the lighting efficiency directly, check the e-\/1N84  
Normalize to emitted flux box and press the Apply button. The map will be $% gz,{  
redisplayed, and the Normalized Flux value will be equal to the lighting efficiency @M'qi=s*  
of the luminaire.

可以看成均匀性吗？
