What is the definition of remote sensing in the context of infrared technology?

The definition of remote sensing in the context of infrared technology is accurately captured by the ability to detect or sense infrared radiation from a target without physical contact. This capability is essential because remote sensing allows for the collection of data and imagery from a distance, often from platforms such as satellites or aircraft. The use of infrared technology in remote sensing can yield valuable information about the thermal characteristics of objects and environments, enabling applications in areas such as environmental monitoring, agricultural assessments, and military reconnaissance.

The essence of remote sensing is that it utilizes sensors to capture IR radiation that is emitted or reflected by various surfaces, thus allowing for the analysis and interpretation of that data. This non-contact approach distinguishes remote sensing from other methods that require direct interaction or measurement alongside a target.
