我不是做背光的,对背光也不太了解 ASZ5;N4u  
我想请教一下,做背光和做一般照明的区别。 6'Yn|A

还不错,挺均匀,不过真够亮的

我也是做背光的,不知为什么,借用一下楼主的图说明一下问题,得到的总是发光强度的分布,不像楼主是照度的分布,请大家指点。。。

How Many Rays Do I Need for Monte Carlo Optimization? `)=A !x y  
While it is important to ensure that a sufficient number of rays are traced to f'6qJk%J  
distinguish the merit function value from the noise floor, it is often not necessary to jUJTcL  
trace as many rays during optimization as you might to obtain a given level of SXBQ  
accuracy for analysis purposes. What matters during optimization is that the ~26s7S}  
changes the optimizer makes to the model affect the merit function in the same way c > mu)('U  
that the overall performance is affected. It is possible to define the merit function so _A,-[*OKI  
that it has less accuracy and/or coarser mesh resolution than meshes used for lii ]4k+z  
analysis and yet produce improvements during optimization, especially in the early Stw+Dm\!  
stages of a design. VyoE5o  
A rule of thumb for the first Monte Carlo run on a system is to have an average of at `@$"L/AJ  
least 40 rays per receiver data mesh bin. Thus, for 20 bins, you would need 800 rays 85|95P.<  
on the receiver to achieve uniform distribution. It is likely that you will need to $}^\=p}X  
define more rays than 800 in a simulation in order to get 800 rays on the receiver. F7Dc!JNa  
When using simplified meshes as merit functions, you should check the before and P10p<@?  
after performance of a design to verify that the changes correlate to the changes of %kZ~xbY  
the merit function during optimization. As a design reaches its final performance rX!+@>4_L  
level, you will have to add rays to the simulation to reduce the noise floor so that }^pQbFku  
sufficient accuracy and mesh resolution are available for the optimizer to find the X(!AI|6Bt  
best solution.
