Study on key technologies of uncooled infrared focal plane array

With its high density, good performance and low cost, non-cold infrared focal plane array (IRFPA) has become the key point at present of studying infrared imaging technology. It will be restricted by such various technological problems as material performance, output circuit, performance parameter test, and image quality to develop non-cold infrared focal plane array detector with big area and even performance. Focusing on the working principle, structure and form, imaging quality of non-cold infrared focal plane array, considering the present achievements, this paper describes the key technological problems of the newest study hot-spots in details.
