A Calculation Method for Response Spectrum of Mercury Cadmium Telluride Infrared Focal Plane Arrays Detector

In this paper, a calculation method for the response spectrum of a mercury cadmium telluride (MCT) infrared focal plane detector was proposed. A calculation approach of the spectrum in the short-wavelength region was proposed considering the relationship between surface recombination and response spectrum. A MCT focal plane infrared detector was fabricated, and the response spectrum was characterized. The experimental results were consistent with the expected results.
