TLDR
Variations on the Koehler illumination system, used for providing light to be reflected from, or transmitted by, an SLM, can be found in this article, where an anamorphic illumination system (10) uses multiple light sources (11) and a cylindrical lens (14) to provide an elongated and compressed beam to the SLM.Abstract:
Variations on the Koehler illumination system, used for providing light to be reflected from, or transmitted by, an SLM. An anamorphic illumination system (10) uses multiple light sources (11) and a cylindrical lens (14) to provide an elongated and compressed beam to the SLM (16). A cascaded illumination system (30) uses multiple light sources (31) and multiple TIR prisms (33) to provide an extended light beam or one that is more intense, to the SLM (36).read more
