    • The thermoelectric detector comprises an infrared absorber pixel structure supported by two electrically connected beams made of a thermoelectric material. One end of the thermoelectric beam connects to the infrared absorber pixel structure; the other end connects to the substrate. The detector comprises a microlens for collecting and focusing infrared radiation on the detector. Infrared radiation is incident on the infrared absorber pixel structure results in a temperature gradient along the length of the thermoelectric legs, and generating an electrical voltage proportional to the gradient. A low noise SIGe BiCMOS readout integrated circuit is coupled to the detector to provide a background limited detector having improved detectivity.

    • A device and method for the detection of one or more gases is disclosed.A MEMS structure comprising a micro gas cell array is provided comprising one or more micro gas cells having a predetermined gas therein. The micro gas cells define an optical path therethrough and may comprise a micro lens. Electromagnetic energy from a scene is collected and passed through one or more micro gas cells whereby electromagnetic energy emitted or reflected from a gas of interest in a scene is absorbed by a substantially identical gas contained within a micro gas cell. In this manner, the micro gas cell acts as a spectral filter.The electromagnetic outputs of the micro gas cells, which may comprise one or more spectrally inert micro gas cells, are received by one or more detector elements such as a photon detector array. The ratio of the outputs of the related detector elements are computed by processing electronics, resulting in the identification of the gas of interest.
