Title: METHOD AND DEVICE FOR OPTIMIZING THE USE OF MULTIPLE EMITTERS AND A DETECTOR IN AN ACTIVE REMOTE SENSING APPLICATION
Abstract:
The invention relates to a method of an optimal arrangement in time and space of nsrc multiple laser emitters 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; - repeating for every emitter k of said plurality of nsrc emitters the steps of: - waiting for a given offset duration toffset,k; - activating both the laser emitter k, with a power output corrected by η-1, and the detector for a duration of τp; - deactivating said emitter k and detector after duration τp; - flagging emitter k to be kept off for the subsequent duration toff = tp - τp. The invention further relates to a device implementing said method.
