Paper Abstract

This paper approaches the fundamental principle and design methods of digital communication system by using CO2 laser to relay through free space, and analyses the principle of acoustic-optic modulator as the key technology in the system, and HgGdTe sensor, low noise amplifier and relay interface circuit. Large-scale programmable integrated device isp1032 is applied to realize the design of no-standard relay interface circuit. The trunking of full-duplex digital communication is realized between the electricity terminals.
