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(lái)的照度圖有什么區(qū)別？哪位能詳細(xì)解答一下。 *w}r:04F

說(shuō)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(lái)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。 12: Q`   
也就是說(shuō)，比如你的總光源有10lm，得出的照度圖在沒(méi)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(lái)的/總流明，可以認(rèn)為是沒(méi)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(shuō)明書么？可以共享一下么？

Normalize ZvK3Su)f1  
Normalize the map data to the total emitted flux from all sources.
0/cgOP!^  
This option allows you to have the flux and irradiance normalized to the total 6.a>7-K}%  
emitted flux. When this box is checked, TracePro divides the values in the kHQn'r6  
irradiance map and the total flux by the emitted flux. This is especially useful for 5bol)Z9BO  
calculating system transmittance for an optical system, or lighting efficiency for a .dvs&+I  
lighting calculation. ZT,auSX  
Example 1: System Transmittance 0t*PQ%  
Suppose you need to calculate the system transmittance of an optical system. R/2L9Lcv  
You would probably use the grid raytrace option, and the emitted flux is equal to $lJ!f  
the sum of the flux in all the emitted rays. When you display an irradiance map, BL%&n*&  
the system transmittance is equal to the total flux, displayed at the bottom of the psS
^  
irradiance map window, divided by the emitted flux. To get the system -vt6n1A&b  
transmittance, check the Normalize to emitted flux box and press the Apply [T,Df&  
button. The map will be redisplayed, and the Normalized Flux value will be equal 9>_VU"T  
to the system transmittance. rAgp
