I have used IDL & MATLAB for simulating/modeling optics in different
optical systems. With that being said, I don't really recommend doing it
in either language as there are no pre-fabricated tools for doing it
quickly. Basically, it amounts to writing code for a bunch of optical
matrices (which you can find in any good optics textbook) and multiplying
them appropriately. "Ray tracing" is nothing more than matrix operations
which both IDL and MATLAB can do easily. However, a programmer must first
understand optical matricies to write code for this...
You should look into some of the free optics packages available on the web
(or something like zemax if you want to do real optics
calculations). However, IMHO you will need a firm grasp of general optics
theory to use any of these tools effectively. Perhaps if you post more
hints as to exactly what you are trying to do, I can dig through my code
and find a suitable example to post.
Cheers,
Randall

My problem is that I have made a light guide to transfer the light from 5
leds to the front panel of a box. In this array the light leaks a lot from
one light guide to the other. I tried to fix this by putting opaque
material all around the guides but this approach reduced the intensity a
_lot_.
So I would like to do some simulations of what would happen if I use a
round piece of plastic instead of a guide made out of polygons. It would
also be nice to see if I could reduce cross-talking by forming some weird
angles from the connecting plastic pieces.
