INFRARED DETECTOR

摘要

An infrared detector of the present invention comprises: a cell array wherein microbolometer cells detecting infrared rays and outputting current signals are arranged in the form of N rows and M columns; a standard cell array wherein standard microbolometer cells not responding to the infrared rays and outputting standard signals are arranged in N rows and one column; and integrators for each of the M columns. In the integrators, the current signals outputted from the microbolometer cells included in the corresponding columns and differential current signals of the standard signals outputted from the standard microbolometer cells corresponding to the rows identical to those of the microbolometer cells are inputted.
