Abstract: It is necessary to measure the spectral responsibility of every single wavelength manually when measuring the relative spectral responsibility of infrared focal plane array. But the process is very complex and timeconsuming. Based on the different platforms, a relative spectral responsibility autotesting system of infrared focal place array was researched by dynamic linking library technology. It will reduce the complicated operation and meet the needs of various device measurement.

Key words: Infrared focal plane, Auto-testing, Dynamic linking library, Relative spectrum responsibility
