  • Patent number: 11812202
    Abstract: An apparatus and method for optically remapping projected pixels to maximize the utilization and to optimize the distribution of remapped projection pixels to achieve optimal visual performance (generally uniform resolution and luminance). A device interposed between a projector and an imaging surface for optically remapping projected pixel locations with minimal aberration. When this device is interposed between a projector and an imaging surface, it changes the terminal location of each focused pixel such that it maximally coincides with the imaging surface, which is often a surface of complex curvature and very different from the native focal surface of the projector. One implementation of the technology includes a device that uses multiple optical surfaces.
