High-speed 3D imaging using a chaos lidar system

Abstract We characterize a new chaos lidar system configuration and demonstrate its capability for high-speed 3D imaging. Compared with homodyned scheme employing single-element avalanche photodetectors (APDs), the proposed utilizes fiber Bragg grating quadrant APDs to substantially increase throughput, frame rate, field-of-view. By quantitatively analyzing signal-to-noise ratio, peak-to-standard deviation of sidelobe level, precision, detection probability, we show that has better performance suitable practical applications. To feasibility system, while under constrain eye-safe regulation, imaging indoor outdoor scenes at throughput 100 kHz, rate 10 Hz, FOV 24.5 $$^\circ $$ ∘ $$\times × 11.5 first time.
