Abstract
A bolometric array detector for detecting electromagnetic radiation in a predetermined range of infrared wavelengths includes a substrate; an array of bolometric micro-plates for detecting the radiation suspended above the substrate by support arms; and metallic reflectors formed on the substrate underneath the micro-plates to reflect that portion of the radiation which has passed through said micro-plates without being absorbed by the latter. For each micro-plate, a corresponding reflector includes a first part located underneath the micro-plate which extends as a second part not positioned underneath the micro-plate. At least the second part has surface texturing in a repeating pattern for coupling a portion of incident radiation on the second part to a guided wave that propagates towards the first part of the reflector positioned underneath micro-plate.
