Design and Realization of InGaAs FPA Imaging Module

The technology of InGaAs short wave infrared (SWIR) imaging is applied in military,security,and some industrial detection applications.This paper designed an InGaAs Imaging Module which based on FPGA technology.In this module,we discussed several kinds of key technologies such as timing driving,temperature stabilization,non-uniformity correction,image enhanced,auto exposal technology and so on.By some test and application work,this module has high sensitivity,strong contrast and clear SWIR image even in foggy weather.
