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 to a lateral anamorphic component arranged to provide imaging of the spatial light modulator in the lateral direction; and an extraction waveguide arranged to receive light from the lateral anamorphic component. partially reflective extraction elements are arranged between the rear and front guide surfaces of the extraction waveguide 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.
