Abstract
A method for determining in situ the thermal conductances of bonding layers of detectors in infrared detector arrays for quality selection of preferred detector arrays. Each detector of the array is heated successively by laser pulses of variable pulse width and the thermally-induced change in detector resistance is measured as a function of time after each laser pulse and converted directly to its corresponding temperature. Using measured values of detector resistance as a function of temperature for each detector, one can obtain the time-dependence of the detector temperature following each laser pulse for each detector of the array.
