  • Publication number: 20220171064
    Abstract: 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.

  • Publication number: 20210405207
    Abstract: A beam transmitter, a receiver, and a LIDAR, along with methods to operate each are provided. The beam transmitter comprises a first and a second transmission channel (201a, 201b), each transmission channel including a first online laser, a first offline laser, and a first laser transmission selection switch operable to toggle between including the first online laser signal and the first offline laser signal in a first transmission beam. The beam transmitter further includes at least one light redirection device operable to coalign the first transmission beam with the second transmission beam. The receiver comprises a first splitter (402a, 402b), a first filter (404a, 404b), a first detector channel (406a, 406b), a second splitter (408a, 408b), a second filter (410a, 410b), and a second detector channel (412a, 412b). The LIDAR includes the beam transmitter, the receiver, and a shared telescope.

  • Patent number: 10794998
    Abstract: 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.

  • Patent number: 10379024
    Abstract: A method for determining a distribution of events, a method for determining a distribution of particle sizes in a sample of air, and an apparatus for performing the same are provided. The method includes obtaining a measured ensemble property distribution function for one or more events, generating one or more theoretical ensemble property distribution functions based on Poisson statistics using one or more model parameters, and determining an event parameter property distribution function by fitting one or more of the theoretical ensemble property distribution functions to the measured ensemble property distribution function using a forward inversion algorithm.
