Abstract
High three-dimensional (3D) resolution for a wide field-of-view (FoV) is difficult in LiDARs because of the restrictions concerning size, weight, and power consumption (SWaP). Using a static unitary detector (STUD) approach, we developed a photodetector and a laser module for a LiDAR. Utilizing the fabricated photodetector and laser module, a LaserEye2 LiDAR prototype for low-SWaP applications was built using the STUD approach, which efficiently enables short-pulse detection with the increased FoV or large photosensitive area. The obtained 3D images demonstrated a diagonal FoV of > 31°, a frame rate of up to 15 Hz, and a spatial resolution of 320 × 240 pixels within a detection range of > 55 m. This prototype can be applied to drones to rapidly detect small or thin hazardous objects such as power lines.
