Patent ID: 11131861

Abstract:
A system and method for retinal image projection are disclosed. The system includes an image projection module that is configured and operable for projecting at least first and second image portions corresponding respectively to first and second parts of an image to be respectively projected on foveal and peripheral regions of an eye retina; and an optical multiplexing module optically coupled to the image projection module and configured and operable to spatially and/or temporally combine/multiplex the projections of the at least first and second image portions for generating a combined image projection output for propagation along a general common optical path which is to be directed towards said eye retina. The optical multiplexing module is configured and operable to multiplex the projections the first and second image portions such that a lateral extent of the combined projection is somewhat similar to a lateral extent of the second image portion in the combined projection which is intended to fall/cover the parafoveal regions of the eye retina, and the lateral extent of the first image portion in the combined projection being smaller and within the lateral extent of the combined projection. The first and second image portions may be projected with different qualities (different resolutions and/or different color depth) and/or with different framerates in accordance with the respective foveal and parafoveally regions of the retina to which there are intended, to the by optimize the image quality/frame rate, and the associated processing and projection capabilities to the anatomical structure of the retina.
