Abstract

A direct modulated VCSEL illumination driver is fabricated and investigated for the compact direct-pulsed LIDAR sensor. The optics for VCSEL illumination includes focusing lenses and micro-lens arrays for flattened beam profile over the entire field of view (FoV) area. The performance of the proposed system is demonstrated in lab environment utilizing a FPGA-based platform. The return pulse from the FoV area is detected by a silicone photomultiplier (SiPM) sensor and a time-to-digital converter. Additional MEMS mirror is utilized for reconstruction of the 3D image up to 10 m.
