WAVEGUIDE WITH HOLOGRAPHIC AND DIFFRACTION OPTICAL ELEMENTS, METHOD FOR MANUFACTURE THEREOF, VIRTUAL AND AUGMENTED REALITY APPARATUS CONTAINING SUCH WAVEGUIDE, AND METHOD FOR OPERATION THEREOF Russian patent published in 2021 - IPC G02B5/32 G02B5/18 

FIELD: waveguides.

SUBSTANCE: invention relates to the field of waveguide-based virtual and augmented reality apparatuses. Claimed is a method for manufacturing a waveguide with diffraction optical elements, including: providing a waveguide, fixing fragments of one or more holographic media on the waveguide; recording a diffraction optical element constituting a holographic optical element in each fragment of the holographic medium using a pre-distorted object wave containing phase-conjugated aberrations to the aberrations of the inspection wave, detected after the inspection wave passes the local structure formed by the waveguide and this fragment of the holographic medium. Also provided is a waveguide with diffraction optical elements manufactured according to the above method, a virtual and augmented reality apparatus containing such waveguide, and a method for operation thereof. Also proposed is a method for manufacturing a waveguide with diffraction optical elements recorded in fragments of one or more recorded diffraction media, a waveguide with diffraction optical elements manufactured according to the above method, a virtual and augmented reality apparatus containing such waveguide, and a method for operation thereof.

EFFECT: provided is compact and cheaper virtual and augmented reality apparatus containing a waveguide with holographic and diffraction optical elements due to elimination of the need for pre- and post-processing of images introduced into the waveguide and the possibility of using non-ideal waveguides and holographic media.
