Abstract

Compared with traditional analog infrared focal plane detector, digital infrared focal plane detector has many technical advantages, which is one of the key directions of digital infrared focal plane detector technology. Firstly, this article introduces the development history of infrared focal plane array detectors, analyzes the differences between analog and digital infrared focal plane array detectors. After that, four different kinds of the current direction of infrared focal plane array technology are introduced. Then, this paper analyzes the structure and performance characteristics of related readout circuits, and summarizes the development and advanced research results of various companies in different array size and pixel pitch. Finally, the future development trend of digital readout circuit technology is stated.
