EYE PROJECTION SYSTEM AND METHOD Russian patent published in 2020 - IPC G02B27/01 

Abstract RU 2728799 C2

FIELD: optics.

SUBSTANCE: projection device comprises a projection system for projecting images on the retina, including an image projection module for superimposing a code, corresponding to image; optical unit, which comprises an input port and an output port, where the optical unit input port is optically conjugated with the image projection module to receive a light beam therefrom, in which the image is encoded, and the output port of the optical unit outputs the said light beam, in which the image is encoded, for its propagation to the eye along the adjustable propagation path; deflector structure consisting of one or more adjustable optical deflectors between input and output ports, which is configured to adjust at least three degrees of freedom of said adjustable light beam propagation path between the output port of the optical unit and the eye. Deflectors are configured with at least three tuned deflection parameters affecting path of said beam propagation path, providing at least three degrees of freedom when adjusting the propagation path of said light beam between the output port and the eye. Two of said at least three degrees of freedom are associated with two angular parameters of orientation of beam propagation path to eye to compensate for changes in direction of view, and at least one of said at least three degrees of freedom is associated with transverse displacement of beam propagation path to compensate for variation of transverse position of said device for projection relative to eye.

EFFECT: system and method for eye projection are disclosed.
