[求助]序列照明下平行光束的优化设计（急求） [复制链接]

嗯，我也想学习呢，不太懂。

automanqing:你要针对你的光源设计透镜，在非序列模式里用source file导入你的LED光源文件，再设计透镜，具体怎么用查manual (2014-09-29 10:31)  ;0m J4G

就是不知道怎么设计啊，在序列里面它是怎么优化的啊？变成平行光，还有光源怎么设置？谢谢！

You can adapt the approach as you put in your post: <Ez@cZ"  
^kcuRJ0*$  
- Get the light source information (ray angle) eSObOG/  
- Set it up in the sequential mode first, with the positions and the initial lens parameters. 7Z:HwZ  
- There is a built in merit function type called Angular Radius what can be useful to design a collimating system. However, you should be aware that the LED source is an extended source and to model it more realistically you should add more field points to represent this nature of the light source. Once you can something close (hopefully) then you can switch it to Non-seqential mode with the real light source file (using Source file) and the lens parameters you came up with under the sequential mode.

- Once this is done you should reoptimize your lenses using relevant operands under non-sequential mode. (the info about this aspect of optimization should be found in the forum.) ]aMDx>OE

Good luck!

Since I don't have a QQ. I will answer you directly in the forum. Regarding your need to optimize uniformity of the illumination. You can try the following setting. ';x5 $5k'

光学设计问题 C5,\DdCX,  
初选光源  LUW CRDP，OSLON r\A|fiL  
目标：照射的时候在半径为12mm的圆斑内均匀性达到80%以上。 ]qb>O:T  
设计方案：先用4盏LED光源进行模拟在半径为90mm的圆周上，与竖直方向的夹角为30度照射到目标面上。 ilRPV'S^  
优化方案：采用坷垃照明原理，光源通过两片平凸透镜，出射光束为平行光。初步计算出两片透镜的参数： A&N$=9.N1  
第一片：曲率半径-7.5mm,孔径5mm，厚度4.6mm B#]:1:Qn  
第二片：曲率半径-18mm,孔径10mm，厚度7.7mm  o,rK8x  
现在序列照明里面优化 ZAJ~Tbm[f  
采用点光源经过两个透镜，使出射光束为平行光,如下图所示，使出射光束为半径12mm的平行光。 RH9P$;.7

第二种方法，先让第一个透镜聚焦，之后再出射平行光，如下图所示： i,zZJ=a$

这个设计的时候优化函数我不知道怎么弄，让第一个聚焦，第二个为平行光出射。 ]`q]\E

而且发现有时候将这种优化后的结果参数调一下之后均匀性比第一种的强，但是这种是不是能量损失比较大？？？（究竟选择哪一种比较合理呢？？？）两者的话均匀性我都没有设计出理想的结果，不知道什么原因，问题究竟在哪？ @.,Mn#

还有把LED光源在序列照明的时候当做点光源来处理，发现和在面上选择几个点差不多，但是合理不？？？ d};[^q6X  
请帮忙解答一下，谢谢！

照明没学过，看不懂
