LIDAR(Light Detection and Ranging) 시스템은 LIDAR 측정 유닛, 기준 측정 유닛 및 위상 제거 유닛을 포함한다. LIDAR 측정 유닛은 레이저 빔이 이동하는 시간을 추정한다. 기준 측정 유닛은 레이저 소스의 위상을 결정한다. 위상 제거 유닛은 레이저 소스의 위상과 레이저 빔이 이동하는 시간에 적어도 부분적으로 기초하여 위상 노이즈를 식별하고 레이저 빔에서 위상 노이즈를 제거한다. 노이즈가 제거된 신호는 레이저 소스와 타겟 사이의 거리를 결정하는 데 이용된다.

    A light detection and ranging (LIDAR) system includes a laser and a calibration unit. The laser is configured to generate a laser beam based on a particular laser waveform that is associated with at least one parameter of a plurality of parameters. The calibration unit is configured to determine a particular value for the at least one parameter of the plurality of parameters to compensate for distortion characteristics of the laser. The calibration unit is configured to determine the particular value based on an output frequency of the laser beam. The calibration unit is configured to update the particular laser waveform with the particular value of the at least one parameter of the plurality of parameters.
