Development of a Low-Noise Three-Dimensional Imaging LIDAR System Using Two 1×8 Geiger-Mode Avalanche Photodiode Arrays
In this paper, a three-dimensional imaging LIDAR system using two 1×8 Geiger-mode avalanche photodiode (GmAPD) arrays is presented. A passively Q-switched microchip laser is used as a light source and a compact PCI (cPCI) system, which includes a time-to-digital converter (TDC), is set up for fast signal processing. Clear 3D images with a fast acquisition speed are obtained by the proposed LIDAR system with using two 1×8 GmAPD arrays for the reduction of false alarms at the TOF data acquisition stage. The software for the three-dimensional visualization is developed for the system of a 1×8 GmAPD array. The range resolution of the system is measured at 100 m, and 3D images acquired by one GmAPD array and two GmAPD arrays during the daytime.
