Abstract

Various techniques are provided for implementing an infrared imaging system. In one example, a system includes a focal plane array (FPA). The FPA includes an array of infrared sensors adapted to image a scene. The FPA also includes a bias circuit adapted to provide a bias voltage to the infrared sensors. The bias voltage is selected from a range of approximately 0.2 volts to approximately 0.7 volts. The FPA also includes a read out integrated circuit (ROIC) adapted to provide signals from the infrared sensors corresponding to captured image frames. Other implementations are also provided.
