The Measurement and Application of the Minimum Detectable Irradiance for the Infrared Point Source Detection System

A procedure and method for the MDI(Minimum Detectable Irradiance) measurement of an infrared point source detection system is described in detail and its experimental result is analyzed. The proposed measurement method for MDI can be realized with a collimator in the laboratory environment. In addition, an estimation method of the maximum detection range of the infrared point source detection system is introduced and its performed result is shown.
