LiDAR METHODS AND SYSTEMS WITH SELECTIVE DENSITY SCANNING BASED ON MEMS

摘要

The disclosed systems, and methods are directed to a LiDAR system comprising a radiation source for emitting an output beam, a microelectromechanical (MEM) component for receiving the output beam and for reflecting the output beam towards the region of interest, the MEM component oscillates at a first oscillation amplitude to spread the output beam by a vertical interval along a vertical axis in the region of interest, a detector for detecting an input beam from the region of interest, a processor configured to determine, from the input beam received by the detector, whether there is an object in the region of interest and responsive to a determination that there is an object in the region of interest, cause the first oscillation amplitude of the MEM component to be modulated to a first modulated oscillation amplitude to reduce the vertical interval of the output beam around the object.
