Abstract
A high-speed light detection and ranging (LIDAR) system includes one or more arrays of transmitting laser diodes (TLD) fixed to a mobile platform; multiple such arrays may be arranged around the mobile platform instead of a single array rotating at high speeds. Each TLD of the array transmits, in sequence, a light pulse at a transmit time to illuminate a particular azimuth and elevation. One or more receiving photodiodes (RPD) are fixed to the mobile platform and configured to receive the reflected returns of the transmitted laser pulses. Signal processors allow the LIDAR system to “see” at high resolution by determining distance and directional information and generating point clouds based on the returned pulses.
