Abstract
The latest three-dimensional imaging results from Voxtel teamed with the University are Dayton are presented using Voxtel’s VOX3D™ series flash lidar camera. This camera uses the VOX3D series flash lidar sensor which integrates a 128×128 InGaAs p-i-n detector array with a custom, multi-mode, low-noise, complementary metal-oxide semiconductor readout integrated circuit. In this paper, results are presented of: short-range (< 10 m) three-dimensional lidar imaging performed at University of Dayton with a fast, low-power eye safe laser (20-μJ per pulse, 10-kHz) in high-bandwidth, windowed region-of-interest mode; and longer range (30 – 150 m) outdoor lidar tests performed at Voxtel with two different eye safe lasers (300-μJ and 3-mJ per pulse, 10-Hz) in full-frame low-bandwidth mode. The VOX3D camera achieves a single-shot timing precision of 23.2 cm and 10.7 cm in high-bandwidth and low-bandwidth modes respectively, with the timing precision in high bandwidth mode being limited by camera electronics. The VOX3D camera has a maximum range of 51 m and 159 m with 300-μJ and 3-mJ lasers in full-frame low-bandwidth mode, respectively.
