Abstract
An infrared detector comprising a plurality of bolometer detectors, bias circuitry for applying a bias to the bolometer detectors, and connectors for connecting the bolometer detectors together to form a network, wherein the bolometer detectors are arranged in an environment at substantially atmospheric pressure. A method for increasing the sensitivity of an infrared detector, having a plurality of bolometer detectors arranged in an environment at substantially atmospheric pressure so as to at least partly compensate for a reduction in the sensitivity of the infrared detector due to conduction of thermal energy from the bolometer detectors through the environment, the method comprising at least one of the steps of connecting the bolometer detectors together in at least one of series and parallel, and operating the bolometer detectors at a DC bias current.
