Abstract

The invention relates to a method of an optimal arrangement in time of a laser emitter and a detector for a remote sensing application, comprising: —setting a target time unit integration time tp; —translating said time unit integration time into a reduced time τp and its corresponding power increase factor η−1; —activating both the laser emitter, with a power output corrected by η−1, and the detector for a duration of τp; —deactivating the emitter and detector after duration τp; —keep emitter and detector off for the subsequent duration toff=tp−τp.The invention further relates to a device implementing said method.
