  • Publication number: 20210325828
    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.

  • Patent number: 10656511
    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.

  • Patent number: 10412372
    Abstract: Systems and methods may include a drone or multiple drones to capturing depth information, which may be used to create a stereoscopic map. The drone may capture information about two trailing drones, including a baseline distance between the two trailing drones. Additional information may be captured, such as camera angle information for one or both of the two trailing drones. The drone may receive images from the two trailing drones. The images may be used (on the drone or on another device, such as a base station) to create a stereoscopic image using the baseline distance. The stereoscopic image may include determined depth information for objects within the stereoscopic image, for example based on the baseline distance between the two trailing drones and the camera angle information.
