Original Abstract Submitted
an anamorphic directional illumination device may provide a near-eye display apparatus or a vehicle external light device. the anamorphic near-eye display device comprises a spatial light modulator with asymmetric pixels; an input transverse anamorphic lens; and an extraction waveguide that passes input light in a first direction between a polarisation-sensitive reflector and rear guide surface to a lateral anamorphic reflector, and to reflect the light back through the extraction waveguide to output through the front guide surface. deflection features are arranged on the front side of the polarisation-sensitive reflector to deflect the reflected light towards the pupil of a viewer, maintaining the directionality of the fan of light rays from the slm and anamorphic imaging system. a thin, transparent and efficient anamorphic display apparatus for augmented reality and virtual reality displays and for scene illumination is provided.
