FPGA-Based N×N adaptive channel for array lidar imager

At present, APD (Avalanche Photo Diode) arrays LIDAR (Light Detection and Ranging) has been broadly accepted as an important means to obtain 3D (Three Dimensional) data. A new method of a scalable adaptive N × N channel communication system is introduced in the paper, which is aimed at improving the transmission rate of APD array LIDAR data. This paper presents the research on multi-channel communication system based on FPGA (Field Programmable Gate Arrays) configuration, which can be realized multi-channel parallel data independent receiving and transmitting. The multi-channel transmission system not only improves the data bandwidth, but also improve the load capacity of the system. The feasibility of multi-channel communication is verified sufficiently in the paper.
