Abstract:
An image forming system includes a spatial light modulator (SLM) including a plurality of pixels. Each pixel is configured to diffract incident light and cause the diffracted light to exit the SLM, where a first diffraction order of light exiting the SLM passes through a first exit pupil and higher diffraction orders of light exiting the SLM pass through additional exit pupils having different positions from the first exit pupil. Control logic operatively coupled to the plurality of pixels is configured to control each pixel to control its modulation of the light incident on the pixel and cause the plurality of pixels to collectively form an image at each exit pupil. A light source is configured to emit incident light toward the SLM. A resampling layer is configured to subsample each pixel electrode with two or more samples per pixel to increase a spacing between each exit pupil.
