Abstract
We have used non-sequential ray tracing as a simulation tool to model micro-optical systems. Ray tracing can be used to model micro-optical systems as long as the wave nature of the light is not dominant. Non-sequential ray tracing takes inherently into account the aberrations of the optical system and enables the modeling of scattering and stray light effects. We have used measured scattering properties of a hybrid-glass lens material to model scattering in an example imaging micro-optical system. We have also used non-sequential ray tracing to model a straight and a bent light-guide that can be used as chemical sensors. Modeling estimates the amount of light going through the optical system to the detector and shows the paths of the rays leaking out from the system.
