Abstract: An optical architecture comprises a refractive cylinder that is movable relative to the incident light. By moving the refractive cylinder, the output light from the refractive cylinder is capable of sweeping through a spatial angle. Examples of the optical architecture can be implemented in an imaging system, such as a display system, for sequentially illuminating the target, such as a light valve in a display system with a high brightness.

Abstract: System and method for thin projection display systems. An embodiment comprises a light source, an array of light modulators optically coupled to the light source, a lensed mirror optically coupled to the array, and a controller electronically coupled to the array and to the light source. The array produces images on a display plane by modulating light from the light source based on image data and the controller provides light commands to the light source and load image data into the array. The lensed mirror reflects modulated light from the array onto the display plane, the lensed mirror comprising a refractive portion and a reflective portion. The refractive portion of the lensed mirror helps to increase the light bending capability to help reduce the overall thickness of a projection display system.
