BOLOMETRIC DETECTOR WITH THERMAL INSULATION BY CONSTRICTION AND INFRARED DETECTION DEVICE USING SUCH A BOLOMETRIC DETECTOR

摘要

P This bolometric detector comprises: - an absorbent part, intended to transform incident electromagnetic radiation into calories, - an active part (2), itself consisting of: • a sensitive zone made of a bolometric material, the resistivity varies, in known manner, with the temperature of electrodes in contact with the bolometric material (6) on at least part of their surface, support zones or pillars (3) intended to maintain said active part (2). ) suspended above a substrate (1) receiving in particular the reading circuit associated with said detector, and to ensure the electrical conduction between said read circuit and said active part, said support zones or pillars (3) having section regions non-uniform between their point of contact with the substrate and their zone of attachment to the active part, or are associated with elements having such non-uniformities. / P
