在Tracepro的照度圖選項(xiàng)中有一項(xiàng)“Normalize to emitted flux”，選擇和不選擇的情況出來的照度圖有什么區(qū)別？哪位能詳細(xì)解答一下。 ;S

說明書：規(guī)范從所有發(fā)光源發(fā)出的所有出射通量給圖的數(shù)據(jù)，這個(gè)選項(xiàng)允許你使通量和光照規(guī)范為總共的通量，如果這個(gè)框被選中后，TracePro在光照度圖中使用出色通量來除以總通量。這對(duì)于在光學(xué)系統(tǒng)計(jì)算的系統(tǒng)透射率和照明系統(tǒng)中計(jì)算發(fā)光效率，會(huì)非常有用。 Kk% IN9  
也就是說，比如你的總光源有10lm，得出的照度圖在沒有選擇norm～選項(xiàng)的時(shí)候是顯示正常的照度，在勾選了之后顯示的照度值是原來的/總流明，可以認(rèn)為是沒流明所產(chǎn)生的照度值

謝謝版主的耐心解答，^_^

哈哈

有中文說明書么？可以共享一下么？

Normalize [58qC:  
Normalize the map data to the total emitted flux from all sources. 0w".o!2\U{  
This option allows you to have the flux and irradiance normalized to the total )tx!BJiZ[  
emitted flux. When this box is checked, TracePro divides the values in the %hA0  
irradiance map and the total flux by the emitted flux. This is especially useful for j[$+hh3:  
calculating system transmittance for an optical system, or lighting efficiency for a FQB6`

lighting calculation. :

Suppose you need to calculate the system transmittance of an optical system. !h+VbZ  
You would probably use the grid raytrace option, and the emitted flux is equal to -pN'r/$3V  
the sum of the flux in all the emitted rays. When you display an irradiance map, o[k,{`M0  
the system transmittance is equal to the total flux, displayed at the bottom of the 7;ddzxR4  
irradiance map window, divided by the emitted flux. To get the system NvJ}|w,Z
