How does a microbolometer work
A microbolometer is an uncooled thermal sensor. High resolution thermal sensors require exotic and expensive cooling methods including stirling cycle coolers and liquid nitrogen coolers. These methods of cooling high resolution thermal imagers expensive to operate and unwieldy to move. Also, high resolution … See more A microbolometer is a specific type of bolometer used as a detector in a thermal camera. Infrared radiation with wavelengths between 7.5–14 μm strikes the detector material, heating it, and thus changing its electrical resistance. … See more There is a wide variety of materials that are used for the detector element in microbolometers. A main factor in dictating how well the device will work is the device's See more Most microbolometers contain a temperature sensitive resistor which makes them a passive electronic device. In 1994 one … See more • Less sensitive (due to higher noise) than cooled thermal and photon detector imagers, and as a result have not been able to match the … See more The two most commonly used IR radiation detecting materials in microbolometers are amorphous silicon and vanadium oxide. A problem with some potential materials is that to create the … See more • They are small and lightweight. For applications requiring relatively short ranges, the physical dimensions of the camera are even smaller. This property enables, for … See more The sensitivity is partly limited by the thermal conductance of the pixel. The speed of response is limited by the thermal heat capacity divided by the thermal … See more WebA microbolometer is a thermal detector that operates by measuring the temperature of a material with a high temperature coefficient of resistance, called a thermistor. The …
