Anamorphic directional illumination device
This abstract first appeared for US patent application 20240427152 titled 'Anamorphic directional illumination device
Original Abstract Submitted
an anamorphic near-eye display apparatus comprises a spatial light modulator with asymmetric pixels; an input transverse anamorphic lens; an input waveguide that passes input light in a first direction to a partially reflective mirror, an intermediate waveguide comprising a reflective lateral anamorphic component arranged to receive light from the partially reflective mirror and to provide imaging of the spatial light modulator in the lateral direction; and an extraction waveguide arranged to receive light from the reflective lateral anamorphic component. reflective extraction elements are arranged to extract the imaged light towards the pupil of an observer, maintaining the directionality of the fan of light rays from the spatial light modulator and anamorphic imaging system. a thin, transparent and efficient anamorphic display apparatus for augmented reality and virtual reality displays is provided.
