  • Multi-chirp pre-distorted laser linearization for FMCW LiDAR
    Patent number: 11874404
    Abstract: What is disclosed are systems and methods for measurement, pre-distortion, and linearization of FMCW (Frequency Modulated Continuous Wave) LiDAR chirped laser signals, in which I/Q channels of an IF optical signal of a combination of delayed and undelayed versions of the laser signal are generated and used in the process of pre-distorting waveform data for linearization.
    Type: Grant
    Filed: July 14, 2021
    Date of Patent: January 16, 2024
    Inventors: Lawrence D. Tzuang, Daniel E. Bush, Christopher T. Phare
