Key milestones include the development of quantum well infrared photodetectors (QWIPs), which improved detection efficiency, and the advent of uncooled IR sensors that reduced the cost and complexity of IR systems. These innovations have paved the way for widespread adoption across multiple industries.

Принципы работы ИК оборудования

At its core, IR equipment operates by detecting infrared radiation emitted or reflected by objects. All objects with a temperature above absolute zero emit IR radiation, with the intensity and wavelength depending on the temperature. This is governed by Planck's law of blackbody radiation.

IR detectors convert this radiation into an electrical signal, which can then be processed to create images or measurements. There are two main types of IR detectors: photon detectors, which respond to individual photons and are highly sensitive but often require cooling, and thermal detectors, which measure changes in temperature and are more robust but less sensitive.

Imaging systems, such as IR cameras, use arrays of detectors to create thermal images. These images can reveal temperature variations, making them useful for applications like building inspections, medical thermography, and industrial monitoring. Spectroscopy with IR light allows for the identification of materials based on their absorption spectra, which is crucial in chemistry and environmental science.

Communication systems use IR light for short-range data transmission, as in TV remotes or infrared data association (IrDA) protocols. The principles of reflection, absorption, and emission are harnessed to design equipment tailored to specific needs.
