Investigation of Ghost Image Effects in Collimation System
In any optical system there are always stray light which causes ghost images. Stray light may come from different effect, like undesired reflections and scattering. A collimation lens system for high-NA laser diode is taken as an example. By using the non-sequential tracing technique in VirtualLab Fusion, the reflections between uncoated surfaces are studied, and it is shown that the multiple reflections may cause interference fringes in the collimated beam.
