Patent number: 11933899Abstract: Through discrimination of the scattered signal polarization state, a lidar system measures a distance through semi-transparent media by the reception of single or multiple scattered signals from a scattering medium. Combined and overlapped single or multiple scattered light signals from the medium can be separated by exploiting varying polarization characteristics. This removes the traditional laser and detector pulse width limitations that determine the system's operational bandwidth, translating relative depth measurements into the conditions of two surface timing measurements and achieving sub-pulse width resolution.Type: GrantFiled: January 24, 2022Date of Patent: March 19, 2024Assignees: The Regents of the University of Colorado, LiteWave Technologies, Inc.Inventors: Jeffrey P. Thayer, Geoffrey Crowley, Andrew W. Gisler, Steven Mitchell, Matthew Hayman

Patent number: 10794998Abstract: Lidar is an acronym for Light Detection And Ranging. The technology may be used to measure distance by illuminating a target with a laser beam and performing analysis on the reflected laser beam light. In the atmospheric sciences, Lidar may be used to study the optical depth of clouds, the impact of aerosols on clouds, and the interactions between aerosols and clouds on the climate. The present application proposes a lidar-based technology using a diode laser (101) beam sent through a tapered semiconductor optical amplifier (106) and an axicon pair expander (108) wherein the laser light may be transmitted through a telescope (110) at an object to be studied. Upon striking the object to be studied, the laser (101) is reflected and recovered by the telescope (110). The reflected laser is then sent through a heated rubidium vapor cell (115) and a total detection channel (116) for analysis.Type: GrantFiled: April 4, 2016Date of Patent: October 6, 2020Assignees: University Corporation for Atmospheric Research, Wisconsin Alumni Research FoundationInventors: Scott Spuler, Matthew Hayman, Bruce Morley, Edwin W.
