Mikrobolometern

Mikrobolometern is a type of uncooled infrared detector that measures infrared radiation and converts it into an electrical signal. It is commonly used in thermal imaging cameras. Unlike cooled bolometers, mikrobolometern does not require a cryogenic cooling system, making it more portable and cost-effective. The core of a mikrobolometern consists of an array of tiny resistive elements, typically made from materials like vanadium oxide or amorphous silicon. When infrared radiation strikes these elements, their electrical resistance changes. This change in resistance is then detected and processed to create a visual representation of the temperature distribution of a scene. The sensitivity of a mikrobolometern is determined by its thermal resolution, which is the smallest temperature difference it can detect. Higher resolution means the device can distinguish finer temperature variations. Mikrobolometern technology has enabled widespread use of thermal imaging in various applications, including security and surveillance, industrial inspection, medical diagnostics, and automotive safety. Its uncooled nature and relatively low manufacturing cost have driven its adoption in consumer electronics and portable devices as well.
