Abstract: A light-sheet generator includes a light focuser and an optical diffuser. The light focuser focuses, in a first horizontal plane, a first beam region of an optical beam to yield a first converging beam having a first divergence angle. The light focuser also focuses, in a second horizontal plane, a second beam region of the optical beam to yield a second converging beam having a second divergence angle that differs from the first divergence angle. Respective centers of the first and the second beam regions are spatially separated in a vertical direction that is perpendicular to both the center axis, the first horizontal plane and the second horizontal plane. The optical diffuser diffuses each of the first and the second converging beam to yield a respective first diffused beam and a second diffused beam that at least partially overlap in a vertical plane that is parallel to the vertical direction.

Abstract: Three-dimensional machine vision system with subpixel precision are provided herein. A system configured to generate a three-dimensional (3D) image of a physical environment. The system comprises a photonic module configured to project a laser line onto a surface in the physical environment, and an imaging device configured to capture a two-dimensional (2D) image of the projected laser line. The photonic module and the surface are in relative motion in a physical y-direction. The 2D image comprising pixel columns extending in an image Y direction, which corresponds to a physical z-direction, and aligned in an image X direction, which corresponds to a physical x-direction. The system comprises a processor configured to identify an edge of the captured laser line with a subpixel precision in the image X direction.

Abstract: An opto-electronic system includes a laser operable to produce a laser beam; an optical element including two or more beam-shaping portions, each of the two or more beam-shaping portions having a different optical property; a beam deflector arranged to sweep the laser beam across the optical element to produce output light; and electronics communicatively coupled with the laser, the beam deflector, or both the laser and the beam deflector. The electronics are configured to cause selective impingement of the laser beam onto a proper subset of the two or more beam-shaping portions of the optical element to modify one or more optical parameters of the output light.
