Infrared imager using room temperature capacitance sensor

An infrared imager includes an array of capacitance sensors that operate at room temperature. Each infrared capacitance sensor includes a deflectable first plate which expands due to absorbed thermal radiation relative to a non-deflectable second plate. In one embodiment each infrared capacitance sensor is composed of a bi-material strip which changes the position of one plate of a sensing capacitor in response to temperature changes due to absorbed incident thermal radiation. The bi-material strip is composed of two materials with a large difference in thermal expansion coefficients.

SENSOR SYSTEM

The invention provides a sensor system (800) for generating a sensor signal (Sout) corresponding to a filtered image of a scene. The system (800) incorporates a multielement array (526) and associated processing circuits for providing element signals in response to images projected onto it and a projecting lens assembly (502) for projecting images onto the array (526). The lens assembly (502) projects differently blurred images of the scene onto the array (526) for generating a measurement signal during a measurement phase and a local spatial average correction signal during a calibration phase. A light-diffusing shutter (522) is used for generating the differently blurred images. The system (800) substracts the measurement and correction signals of each element from one another to provide a difference signal and uses this signal to generate the sensor signal (Sout) during the measurement phase. The calibration phase is repeated on change of array temperature or incident radiation intensity ...

MULTIPLE FIELD OF VIEW SENSOR

Images of two fields of view of one or two scenes in a radiation sensor are generated by use of a single detector and common signal process circuitry. The two imaged fields of view, typically a narrow view and a wide view, are provided by two independent telescopes (18, 20), and are combined by use of a field-of-view switch (32) comprising a chopper wheel (34) or an optical switch in synchronized operation with a mirror scanner (22). The same field-of-view switch is employed in performing detector non-uniformity correction functions, such as automatic responsivity control and direct current restoration. Folding optics couples scanned radiation from the scanner to the switch. An additional field of view may be introduced by displacing a folding mirror of the folding optics. Also, a portion of a reflecting surface of the switch may be tilted to admit a reference beam of radiation useful in performing the functions of responsivity control and D.C. restoration.
