Based on a self-designed TDI linear infrared focal plane digitization readout circuit,a infrared focal plane test system with driving IRFPA device and collecting digital data function is designed.Noise analysis of linear digitization readout circuit electric injection method,medium wave infrared focal plane and long wave infrared focal plane is done;NETD that is important for infrared detector is also analyzed.The influences of integration time,focal plane array injection region and bias voltage on the infrared detection performance are discussed respectively.
