Abstract: A microbolometer unit cell (10) includes a substantially planar upper-level incident radiation absorption and detection structure (24), a substantially planar middle-level radiation reflection structure (26) spaced apart from the upper-level incident radiation absorption and detection structure for defining an optical resonant cavity (36) there between and a substantially planar lower-level thermal isolation leg structure (20) spaced apart from the middle-level radiation reflection structure and electrically coupled to the upper-level incident radiation absorption and detection structure and to an underlying readout circuit. The lower-level thermal isolation leg structure is electrically coupled to the upper-level incident radiation absorption and detection structure through a leg (44) that passes through an aperture (48) within the middle-level radiation reflection structure, the leg also functioning as a structural support member. The lower-level thermal isolation leg structure is electrically coupled to the readout circuit through another leg (18) that terminates on an electrical contact (16) disposed on an underlying readout integrated circuit (12), and the middle-level radiation reflection structure is supported by an extension of the leg (18A). It is within the scope of these teachings that the upper-level incident radiation absorption and detection structure includes a stiffening member (50), such as one disposed frame-like about a periphery of the upper-level incident radiation absorption and detection structure. The resonant optical cavity is defined by a spacing that is a function of a wavelength of the incident radiation, and an adjacently disposed unit cell of an array of unit cells may have a resonant optical cavity having a different spacing, thereby providing enhanced sensitivity to a different wavelength.

Abstract: An infrared radiation detection device is characterized by selecting a material which can be laminated with a thermal process, for example, a plastic-based material such as polyethylene (PE) or polyvinylchloride (PVC), to form the substrate of the infrared radiation device. The infrared radiation detection device combines the phosphors powder and the nonlinear crystal powder as the source for detecting the infrared radiation, thereby the infrared radiation detection device is capable of detecting the infrared radiation at different power level and different visible wavelengths. The active area of the infrared radiation detection device which includes an infrared radiation detection thin film is coated or printed onto the substrate in a margin-to-margin manner, such that the incident infrared radiation glares which is reflected from the surface of the non-active area of the infrared radiation detection device is reduced.

Abstract: Electro-thermal feedback is utilized for removing thermal conductance between a bolometer's absorber element of a pixel in a thermal radiation sensor assembly and the environments through its mechanical support structure and electrical interconnects, thereby limiting the thermal conductance primarily through photon radiation. Zeroing the thermal conductance associated with the mechanical support structure and electrical interconnects is achieved by electro-thermal feedback that adjust the temperature of an intermediate stage of the mechanical support structure and electrical interconnects to equal the bolometer's absorber element temperature.
