ABSTRACT:
A multi-element infrared detector for thermal imaging, wherein the detector includes a main substrate, an aperture plate and a plurality of detector elements formed on the main substrate and arranged thereon in an array. Each detector element having a photosensitive zone and output and common terminal electrodes formed at opposite ends thereof. The aperture plate having at least one aperture for restricting the field of view of the photosensitive zone. The detector includes an auxiliary electrode formed on the rear surface of the aperture plate in a position to contact the common terminal electrodes when the device is assembled. The infrared detector also includes a common metal line formed on the substrate in a position to interconnect a plurality of common terminal electrodes and the auxiliary electrode contacts the common metal line.
