Detector for electromagnetic radiation with reduced sensitivity to spatial noise

摘要

The device (30) has multiple element detectors (32, 62) that are regrouped into multiple sub assemblies (300), where the element detectors are bolometer, microbolometer, photodiode or photoconductor. Each element detector is connected to an impedance adaptation device by interconnections (301 302), where the interconnection comprises same resistance valve in each sub-assembly. Each element detector is in series with switches (34, 340). Each element detector is connected to a source electrode of a matching transistor of the sub-assembly.
