  • Patent number: 11933896
    Abstract: In an optical distance measuring apparatus, a light source irradiates a target object with a light pulse having a first pulse width. A light receiver outputs a pulse signal that represents reflection light from the target object being incident on the light receiver, and has a second pulse width that is larger than or equal to the first pulse width. A histogram generator records, every predetermined period, a frequency representing the number of outputted pulse signals to thereby generate a histogram. A peak detector detects, from the histogram, an edge point of a peak figure included in the histogram. A distance calculator subtracts, from a time indicative of the edge point of the peak figure, a time length of the second pulse width to thereby calculate a target time, and calculates a distance to the target object as a function of the calculated target time.

  • Patent number: 11874379
    Abstract: A system and method of LIDAR imaging to overcome scattering effects pulses a scene with light pulse sequences from a light source. Reflected light from the scene is measured for each light pulse to form a sequence of time-resolved signals. Time-resolved contrast is calculated for each location in a scene. A three-dimensional map or image of the scene is created from the time-resolved contrasts. The three-dimensional map is then utilized to affect operation of a vehicle.

  • Patent number: 11754683
    Abstract: The present disclosure is directed to imaging LiDARs with separate transmit (Tx) and receive (Rx) optical antennas fed by different optical waveguides. This pair of optical antennas can be activated at the same time through a dual-channel optical switch network, with the Tx antenna connected to a laser source and the Rx antenna connected to a receiver. The Tx and Rx antennas can be positioned adjacent to each other, so they point to approximately the same far-field angle. No optical alignment between the Tx and Rx is necessary. This LiDAR configuration, referred to herein as pseudo-monostatic LiDAR, eliminates spurious reflections and increases the dynamic range of the LiDAR.
