Infrared-based refers to any technology, process or device that primarily relies upon or utilizes infrared radiation. Infrared (IR) radiation occupies the portion of the electromagnetic spectrum with wavelengths longer than visible light (roughly 700 nm to 1 mm). Materials that absorb or emit IR are characterized by their temperature and molecular composition and can be detected with specialized sensors.

The term is commonly applied in several fields. In medical imaging, infrared thermography is used to uncover abnormal heat patterns associated with inflammation, vascular disorders, or tumors. Therapeutic infrared devices deliver heat to deepen tissue, reduce pain, and accelerate healing. In environmental sensing, IR spectroscopy identifies gases, pollutants, and atmospheric constituents through their unique absorption lines. Infrared cameras are integral to night‑vision and security systems, allowing detection of bodies and objects in low-light conditions. Industrial processes use IR sensors for temperature monitoring, quality control of manufactured parts, and for detecting faults in machinery through thermal imaging. Consumer electronics such as remote controls and wireless communication protocols (e.g., Wi‑Fi 802.11o in manufacturing) also exploit infrared wavelengths.

The development of infrared technology began with thermodynamic studies in the 19th century and accelerated after the invention of the first IR detector in the early 20th century. Advances in semiconductor materials and sensor fabrication have continually improved the sensitivity, resolution, and affordability of IR devices. However, IR signals are susceptible to atmospheric absorption and scattering, limiting their effective range in some applications. Additionally, IR imaging often requires calibration and can be influenced by ambient temperature, necessitating careful system design. Overall, infrared-based systems provide non‑invasive, real-time insight into thermal and compositional characteristics across a broad spectrum of scientific, medical, industrial, and everyday applications.
