This paper considers the use of non-rotationally symmetric freeform Fresnel lenses for arbitrary shaped optical wireless communication channels. Transmitter and receiver lens design is discussed and design examples for rectangular channels are presented. The optical design procedure includes ray mapping methodology and the edge-ray principle. Optical raytracing simulations with realistic models are used for model validation.
