Patent number: 11867713Abstract: An optomechanical inertial reference mirror combines an optomechanical resonator with a reflector that serves as an inertial reference for an atom interferometer. The optomechanical resonator is optically monitored to obtain a first inertial measurement of the reflector that features high bandwidth and high dynamic range. The atom interferometer generates a second inertial measurement of the reflector that features high accuracy and stability. The second inertial measurement corrects for drift of the first inertial measurement, thereby resulting in a single inertial measurement of the reflector having high bandwidth, high dynamic range, excellent long-term stability, and high accuracy. The reflector may be bonded to the resonator, or formed directly onto a test mass of the resonator. With a volume of less than one cubic centimeter, the optomechanical inertial reference mirror is particularly advantageous for portable atomic-based sensors and systems.Type: GrantFiled: February 15, 2020Date of Patent: January 9, 2024Assignees: Arizona Board of Regents on Behalf of The University of Arizona, Leibniz Universität HannoverInventors: Felipe Guzmán, Ernst Maria Rasel, Dennis Schlippert

Patent number: 11551342Abstract: A test fixture (10) for heads-up windshields (12) wherein aspherical devices (26) compensate for complex curvatures and optical aberrations in a heads-up display surface (16) of the windshield. A movable test grid (20) adjusts the elevation of preferred camera settings and a pivotal mounting of the test grid (20) enhances ghost image reduction and improves camera image resolution. A filter (36) limits interference of secondary ghost images (caused by IR coatings) with compliance assessment of the windshield.Type: GrantFiled: April 2, 2020Date of Patent: January 10, 2023Assignee: Pittsburgh Glass Works, LLCInventors: Andres Enrique Gudino Gandra, Felipe Guzman Botero, Anel Garza Rivera
