Design On 8-12 μM HgCdTe Detecting Circuits Of CO_2 Lasers Atmosphere Digital Communication System

摘要

With the development of light communication technology, the light communication in airspace will be a research field, which awaits energetic research and is of great application value in recent years. However, the research on CO_2 laser atmosphere digital communication system is still in infancy phase in our country from-now on This paper discusses more copiously the specialities and working manners of 8~12 μm HgCdTe Detecting Circuit, and along with the design on preamplification circuit from a practical angle.
