Patent ID: 7750301

Claim:
An infrared camera system comprising: an optical element adapted to pass infrared frequencies of a first range of wavelengths and block infrared frequencies of a second range of wavelengths; a substrate; a plurality of microbolometers coupled to the substrate to form corresponding microbolometer resonant cavities, wherein the microbolometers are disposed to receive the first range of wavelengths passed by the optical element; a plurality of reflective layers disposed on the substrate and corresponding to the plurality of microbolometers; and at least one voltage source adapted to provide a variable voltage potential to vary a spacing of the microbolometer resonant cavities between the reflective layers and the corresponding microbolometers, wherein the at least one voltage source is adapted to provide at least a first voltage potential during a calibration process of the microbolometers to set the spacing corresponding to the microbolometers detecting the second range of wavelengths.
