Abstract:
A system for testing thermal response time of an uncooled infrared focal plane detector array and a method therefor is provided. The system comprises: a blackbody, a chopper, a detector unit under test and a testing system. The method comprises: emitting radiation by the blackbody, chopping by the chopper, then radiating the radiation to the uncooled infrared focal plane detector array under test; generating different responses on the radiation at different chopping frequencies by the uncooled infrared focal plane detector array under test; collecting different response values of the uncooled infrared focal plane detector array under test at different chopping frequencies; obtaining response amplitude at a corresponding frequency in a frequency domain by FFT; fitting according to a formula Rv  ( f ) = Rv  ( 0 ) 1 + ( 2  π   f   τ ) 2 to obtain the thermal response time.

Claim (Index 1):
A system for testing thermal response time of an uncooled infrared focal plane detector array, comprising: a blackbody, a chopper, a detector unit under test and a testing system; wherein the detector unit under test comprises an uncooled infrared focal plane detector array under test and an adapter plate; a center of a radiating surface of the blackbody directly faces a center of the optical lens; the center of the blackbody directly faces a center of the uncooled infrared focal plane detector array under test, the chopper is provided between the blackbody and the detector unit under test; the system for testing thermal response time of the uncooled infrared focal plane detector array controls status of the blackbody, the chopper and the detector unit by external interfaces provided on the blackbody, the chopper and the detector unit; data outputted by the detector under test is transmitted to the system for testing by a data acquisition card.
