Abstract: A device includes at least one processor configured to partition a source image including image components into sub-images, each including a corresponding image component of the image components, and process each sub-image to produce a target image to be projected for each sub-image of the sub-images. The device also includes one or more light sources coupled to the at least one processor and configured to project an incident light, and a phase projection-based display device coupled to the at least one processor and optically coupled to the one or more light sources and configured to modulate, based on the target image of each sub-image, the incident light to separately project the sub-images.

Abstract: A projection system includes: an illumination source configured to output illumination light; a phase light modulator (PLM) optically coupled to the illumination source, the PLM configured to: receive the illumination light; phase modulate the illumination light while displaying a phase hologram, to produce modulated light; and projection optics coupled to the PLM, the projection optics configured to receive the modulated light and to project an image responsive to the modulated light; wherein both a mean in intensity and a variance in intensity in bright regions of the projected image is greater than the mean intensity and the variance in intensity in dark regions of the projected image.
