1. A method for compensating for vibration in a lidar system, the method comprising:

  • emitting light pulses by a light source in the lidar system;

    generating a drive signal for a scanner in the lidar system to direct the light pulses across a field of regard of the lidar system toward different points within the field of regard;

    determining an amount of vibration at the lidar system via an accelerometer, gyroscope, or inertial measurement unit (IMU);

    generating a compensation signal that reduces effects of vibration on the scanner based on the determined amount of vibration; and

    combining the drive signal for the scanner with the compensation signal.
