Modern microbolometers measure temperature changes caused by IR absorption in individual pixels, which are thermally isolated and assembled into focal-plane arrays (FPAs).

The most common form of thermal imaging technology available today is the microbolometer sensor. Microbolometers are built using vanadium oxide (VOx) or amorphous silicon (a-Si) processes. Typical prices for microbolometer -based cameras range from $0to $20depending on resolution, performance and . In certain high-end applications, these constraints are acceptable. For example, the military often demands higher-performance technology than microbolometers can deliver at long distances.

These applications will continue using less portable, more expensive cooled thermal imaging systems that do not provide instant-on . Each Optotherm Infrasight camera contains an infrared detector called a microbolometer. Each array element is approximately x 17µm (x 25mm) in dimension.

What does BOLOMETER mean? After some brief microbolometer technological backgroun we present the characterization of µm pixel-pitch detec- tor as well as the wide-band 320´2infrared focal plane arrays with a pixel pitch of µm.

Drawing on its extensive experience in microbolometric detector design, fabrication, and characterization, as well as in detector-to-ROIC (Read-Out Integrated Circuit) monolithic integration, INO is proud to offer its 3x 2pixel microbolometer FPA (Focal Plane Array) in short series.

Users of thermal imaging cameras should get the best and most modern tech- nology if they decide to purchase a system . A detailed thermal behavior and theoretical analysis of uncooled resistive microbolometer is presented along with the proposed thermal imager simulator. This uncooled microbolometric . An accurate model of a thermal detector is required to design a readout circuit that can compensate for the noise due to process variability and . CMOS process, where the CMOS n-well layer is used as the infrared sensitive material. The n-well is suspended by front-end bulk-micromachining of the fabricated CMOS dies.

Abstract: An uncooled microbolometer -array thermal infrared camera has been incorporated into a remote sensing system for radiometric sky imaging. The radiometric calibration is validated and improved through direct comparison with spectrally integrated data from the Atmospheric. Emitted Radiance Interferometer.

Vanadium oxide thin films are the potential candidates for uncooled microbolometers due to their high temperature coefficient of resistance (TCR) at room temperature. A 2D array of 10-element test microbolometer without air-gap thermal isolation structure was fabricated with pulsed laser deposited vanadium .
