METHOD FOR ESTIMATING THE SPECTRAL RESPONSE OF AN INFRARED PHOTODETECTOR

摘要

A method (1) is described for the estimation of the spectral response of an infrared photodetector (32) that starts with response measurements of the infrared photodetector (32) obtained by varying the temperature of the black body (31) and is such as to estimate the spectral response by solving a numerical matrix problem. The method (1) is fully automatable and presents a cost reduction compared to the known methods because it does not require the use of a monochromator or a circular filter.
