A method and system for operating a LiDAR system for an environment detection in a field of view (FOV) of the system, wherein the following steps are performed: detection of at least one temperature measurement, which differs from a loading temperature in at least one light source of the system, estimation of the loading temperature based on the temperature measurement using an evaluation function, specification of an operating limit, which is specific for the maximum thermal load capacity of the light source, provision of a preset for at least one region of interest (ROI) in the field of view (FOV), adjustment of an operation of the system, and based on the preset for the region of interest (ROI) and the estimated loading temperature and the operating limit.

Method for operating a LiDAR system

A driver circuit for laser diodes is provided with first and second terminals for the laser diodes. The driver circuit also includes capacitors, each being assigned to a laser diode, and at least one input for connection to a charging means. Further included is at least one input for a control signal and at least one first switch means. Each capacitor is connected to the input for connection to the charging means, and a first terminal of each capacitor is connected to the first terminal for the laser diode. The second terminal for the laser diode is connected to a first terminal of the at least one first switch means, and a second terminal of each capacitor is connected to ground. A second terminal of the at least one first switch means is connected to ground and wherein the at least one input for a control signal is connected to a control terminal of the at least one first switch means.
