PREAMBLE PULSE BASED LIDAR SYSTEMS AND METHODS

The disclosed systems, structures, and methods are directed to a LiDAR system comprising a radiation source configured to emit light pulses towards a region of interest (ROI), a detector configured to detect light pulses reflected from the ROI, a processor, communicatively coupled to the radiation source and the detector, configured to cause the radiation source to emit a preamble light pulse having an energy Eand a pulse width Wtowards the ROI, determine, if the preamble light pulse is detected by the detector and whether there is an object in the ROI, responsive to a determination that there is an object in the ROI, cause the radiation source to emit a scanning light pulse having an energy Eand a pulse width Wtowards the ROI, else the radiation source to emit a scanning light pulse having an energy Eand the pulse width Wtowards the ROI.
