1. A method for controlling output of a Laser Imaging, Detection and Ranging (LIDAR) system, the method comprising:
- automatically measuring range to one or more targets in a field of view;
determining the closest one of the targets based on the measured range; and
adjusting at least one of pulse repetition frequency, pulse amplitude, power, pulse duration, or optical intensity of a laser device based on the measured range of the closest target in order to comply with predefined human tissue safety model.

Abstract
A Laser Imaging, Detection and Ranging (LIDAR) system that automatically adjusts laser output so that no eye damage occurs to human targets. In one example, a component automatically measures range to targets in a field of view and determines the closest targets based on the measured range. A laser device outputs a laser beam and a controller adjusts one of pulse repetition frequency, power, or pulse duration of the laser device based on the measured range of the closest target in order to comply with a predefined eye safety model.
