Abstract

This paper discusses the development and measured performance of a high-density infrared staring camera operating with outstanding performance over the entire 3-5 micrometers band. The camera has demonstrated excellent night and thermal vision in a multitude of conditions including penetration through weather and over water. Hybrid focal plane technology was used to construct the 256 X 256 area array. Backside illuminated Indium Antimonide detectors are interconnected using Indium bumps to an advanced CMOS readout integrated circuit. The hybrid format yields high detector fill factor (>90%) and quantum efficiency (>50%). This approach has resulted in an infrared focal plane which has greater than 95dB dynamic range and is background limited (BLIP) for most applications. The paper also covers the integration of the device into a small low power cryogenic dewar as well as the interface and video electronics used to provide remarkable infrared image quality.
