摘要
Abstract
According to the requirements, an active infrared system is designed, which is composed of the emitting and receiving parts. The emitting part consists of a GaAs semiconductor laser device and binoculars optical system. A Si photodiode is selected as the receiving device, and a preamplifier circuit is designed to match the detector and further improve the signal to noise ratio. The laser-encoding mode is utilized to enhance the anti-disturbance. The theoretical analysis of this system is presented and a system prototype is made according to the requirement. The experimental results agree well with the theoretical prediction.
