Abstract: Methods and apparatus to calibrate spatial light modulators are disclosed. Examples include processor circuitry to execute and/or instantiate instructions to provide a greyscale image to a spatial light modulator (SLM) to define voltages to be applied to individual pixels of the SLM. The voltages associated with pixel values in the greyscale image. The pixel values arranged in a double-slit grating pattern. The SLM to produce an interference pattern based on the double-slit grating pattern. The processor circuitry is to determine a phase difference between first and second gratings of the double-slit grating pattern based on the interference pattern. The processor circuitry is to generate a phase curvature based on the phase difference.

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.
