ABSTRACT:
An IR detector for use in an array of detectors is provided with better thermal resolution resulting in increased range and increased contrast for a standard 30 frame per second frame rate includes a support structure for the detector made from thermoelectric material supports which transports heat away from the detecting material during each readout cycle just after the instantaneous reading has been made. By removing heat thermoelectrically from the detector, detector sensitivity is improved, higher frame rates are achievable and an improved fill factor is the result of being able to more closely pack the detector elements.
