Not enough intersections allocated to finish ray trace 在zemax非序列模式下改變截止折射率經(jīng)常會出現(xiàn)Not enough intersections allocated to finish ray trace，請問各位大大這是什么原因造成的是因為我設(shè)計的結(jié)構(gòu)讓光線無法追跡么？ aw~h03R_Z 5X>~39(r [attachment=54877] Gf:dN_e6.

求大神幫我看看~提醒一下~

Under General > Non-Sequential tab, you will be able to set the maximum ray intersections per ray. If a ray encounters a surface of an object it counts as 1 intersection and if you are tracing "split rays" and also have "use polarization" then you could reach the maximum you set under this tab.Increasing this number would help to solve but you dont want to set it too high as it will use a lot of memory and trace the ray section that only carry small negligible amount of energy. Alternatively, you can also change the minimum energy threshold for non-sequential ray tracing so that the ray tracing will terminate at this energy threshold. Again watch out the minimum energy detectable. Hope this helps!!

i found that it does'nt work,if i choose the way you told .if i maxmum the core of fiber ,then the pronlem can be fixed ,but i dont know why ,can you tell me ?

你可以參考一下這里http://zemax.com/support/knowledgebase/what-does-not-enough-segments-allocated-to-trace-a 不知道能不能幫上你。我之前做的出現(xiàn)這個現(xiàn)象是因為發(fā)生了全反射，而我設(shè)置成無限次全反射，所以發(fā)生全反射時報錯，應(yīng)該設(shè)置成全反射光能夠從平板中出去，而不是無限次全反射

感謝。讀了這個才真正了解光線分解面的作用。

olivezh	2014-06-17 20:21
原來是光線在遇到分界面的時候，會分解成多束光，從而導(dǎo)致一個光線在傳播的過程中最終會被分解成為多個光線樹，使得計算量幾何上升，導(dǎo)致仿真報錯。

the maximums are not increased to a sufficient level. z[_Y,I 我的也出現(xiàn)過，然后設(shè)置maximum intersections per ray為4000，Maximum Segments Per Ray為10000，這個可能跟電腦配置內(nèi)存大小有關(guān)系，然后我的就不再提示了

節(jié)點數(shù)量不足，解決方法是Under General > Non-Sequential tab, you will be able to set the maximum ray intersections per ray.
