mikrobolometreilla

A mikrobolometer is a type of thermal detector that measures infrared radiation. It operates by absorbing incident infrared energy, which causes a temperature change in the detector material. This temperature change is then converted into an electrical signal. Microbolometers are widely used in thermal imaging cameras for applications such as night vision, industrial inspection, and medical diagnostics. They are typically made of semiconductor materials that exhibit a significant change in electrical resistance with temperature, such as vanadium oxide or amorphous silicon. The small size and low power consumption of microbolometers make them ideal for portable and compact imaging systems. Unlike other infrared detectors, microbolometers do not require cooling, which simplifies their design and reduces operational costs. The performance of a microbolometer is often characterized by its noise equivalent temperature difference (NETD), which represents the smallest temperature difference the detector can distinguish from its own noise. Higher NETD values indicate poorer performance. The development of microbolometers has been crucial in making thermal imaging technology more accessible and widespread.
