Mikrombolometer
Mikrombolometer, commonly called a microbolometer, is a type of uncooled infrared detector used to form thermal imaging cameras. Unlike cooled infrared detectors, microbolometers operate at or near room temperature and do not require cryogenic cooling. They sense infrared radiation by converting absorbed energy into heat in a thin-film thermistor, which produces a change in electrical resistance.
A typical microbolometer pixel consists of a thin-film absorber on a thermally isolated micro membrane, often
Operation involves biasing the thermistor and reading out resistance changes as voltage signals, which are then
Applications include security and surveillance, industrial inspection, firefighting, automotive night vision, and medical or building diagnostics.
