ABSTRACT:
Fast microbolometer pixels integrating micro-optical focusing elements are provided. Each microbolometer pixel includes a focusing element located between the pixel body and a substrate, this focusing element preferably sending radiation back towards the central portion of the microbolometer. There is also provided a microbolometer array having a plurality of such microbolometer pixels. Advantageously, to increase the pixel speed, the present microbolometers may be built smaller than the detector and no additional structures need to be attached to said detector.
