Abstract: Techniques related to generating holographic images are discussed. Such techniques include application of a hybrid system including a pre-trained deep neural network and a subsequent iterative process using a sui table propagation model to generate diffraction pattern image data for a target holographic image such that the diffraction pattern image data is to generate a holographic image when implemented via a holographic display.

Abstract: A light pattern projector with a pattern mask to spatially modulate an intensity of a wideband illumination source, such as an LED, and a projector lens to reimage the spatially modulated emission onto regions of a scene that is to be captured with an image sensor. The projector lens may comprise a microlens array (MLA) including a first lenslet to reimage the spatially modulated emission onto a first portion of a scene, and a second lenslet to reimage the spatially modulated emission onto a first portion of a scene. The MLA may have a fly's eye architecture with convex curvature over a diameter of the projector lens in addition to the lenslet curvature. The pattern mask may be an amplitude mask comprising a mask pattern of high and low amplitude transmittance regions. In the alternative, the pattern mask may be a phase mask, such as a refractive or diffractive mask.

Abstract: Systems, devices, and techniques related to projecting dynamic feature patterns onto a scene for use in stereoscopic imaging are discussed. Such techniques may include implementing a dynamic transmissive element in an optical path between a projector and the scene to modify a static pattern emitted from the projector to illuminate the scene with a dynamic pattern.

Abstract: A failsafe pulsed laser driver and method for using the same are disclosed. In one embodiment, an apparatus comprises a laser array having a plurality of lasers; and a laser driver coupled to the laser array, wherein the laser driver comprises a current limiter to provide a maximum current at or below a threshold current of lasers in the laser array or at a current level to meet laser safety requirements under circuit failure conditions; one or more capacitors coupled to current limiter and the laser array, the one or more capacitors to be charged in response to current from the current limiter; and a switch coupled to the one or more capacitors operable to cause current from the one or more capacitors to flow through the laser array.
