Abstract

A microstructured sensor for detecting IR radiation includes: one measuring channel having a measuring diaphragm, on which a first sensitive detector surface is implemented for the absorption of a first IR radiation; and one reference channel having a reference diaphragm, on which a second sensitive detector surface is implemented for the absorption of a second IR radiation. A measuring structure, e.g., a thermopile measuring structure as a series circuit made of thermocouple pairs, is implemented between the measuring diaphragm and the reference diaphragm for measuring a temperature differential between the measuring diaphragm and the reference diaphragm. First and second thermal contacts lie alternately on the two diaphragms.
