Do you think POV can be used to model optic phenomena?
In detail I would like to model a light guide: giving the geometri of the
glass guide, and the source at one end I would like to measure the light
energy emetted at the second end.
Do you think it is possible to obtain the value of the energy escaping or
hitting a surface?
Thank you for your help

Unfortunately POV-Ray is not designed for physics simulation, it rather
tries to provide funtionalities that allow artists to make things LOOK
LIKE real. So you won't be able to do what you want.

Actually POV-Ray does many things much more physically accurately than
most scanline renderers. For example sharp reflections are usually quite
inaccurate in scanline-renderers, but physically very accurate in POV-Ray
(same goes for refraction, except for dispersion effects). Photon mapping
is also quite accurate (at least if you shot lots of photons).
The easiest way of getting an image to look like real is to simulate
reality as far as possible, and that's what POV-Ray often does.

Right, but it does take a lot of shortcuts, and a lot of unrealistic
features...you have to know how to set up a realistic scene. Also, the
end result is a nice-looking image, while in optics simulations you
might want data like angle of incidence for an individual ray, total
incident energy on an area of surface, light path length, etc.
