Researchers have observed that among all forms of radiant heat, only far-infrared radiation transfers energy solely in the form of heat that can be sensed by the human body.[12] They have found that this type of radiant heat can penetrate the skin up to a depth of approximately 1.5 inches (3.8 cm). In the field of biomedicine, experiments have been conducted using fabrics woven with FIR-emitting ceramics embedded in their fibers. These studies have indicated a potential delay in the onset of fatigue induced by muscle contractions in participants.[13] The researchers have suggested that the emission of far-infrared radiation by these ceramics (referred to as cFIR) could facilitate cellular repair.

Certain heating pads have been marketed to provide "far infrared" therapy, which is claimed to offer deeper penetration.[citation needed] However, the infrared radiation emitted by an object is determined by its temperature. Therefore, all heating pads emit the same type of infrared radiation if they are at the same temperature. Higher temperatures will result in greater infrared radiation, but caution must be exercised to avoid burns.

Hyperspectral sensors pose an advantage over multispectral sensors in their ability to identify and quantify molecular absorption. The high spectral resolution of a hyperspectral imager allows for detection, identification and quantification of surface materials, as well as inferring biological and chemical processes.

Infrared heating (IR) is a method of heating an area through more efficient results than gas or electric convection heating. Studies show IR heats faster, more uniformly, and more efficiently than a traditional conventional system.[7][8] Increasingly, IR heating is utilised as part of scheme designs to achieve spot, zonal and smart heating within occupation zones within a building.[7] Though multiple applications of long wave or FIR heating exist, a common representation comprises radiant panel heaters. Radiant panel heaters typically contain a grid of resistance wire or ribbons which are sandwiched between a thin plate of electrical insulation on an emitting die and thermal insulation on the back side.[9] Owing to their size and flexibility,[10] infrared panel heaters can be fitted on walls and ceilings for added-space saving benefits. Electric FIR panel heaters are shown to have up to 98.5% efficiency from supply to production of heat with satisfactory thermal comfort, thermostatic control, and with low initial investment.[11]

The brightness observed in far infrared images of the center of the Milky Way galaxy arises from the high density of stars in that region, which heats the surrounding dust and induces radiation emission in the far infrared spectrum. Excluding the center of the Milky Way galaxy, the galaxy M82 is the most prominent far-infrared object in the sky, with its central region emitting amounts of far infrared light equivalent to the combined emissions of all the stars in the Milky Way. As of 29 May 2012[update], the source responsible for heating the dust at the center of M82 remains unknown.[3]

Multispectral remote sensing involves the acquisition of visible, near infrared, and short-wave infrared images in several broad wavelength bands.

Hyperspectral imaging systems acquire images in over one hundred contiguous spectral bands. While multispectral imagery is useful to discriminate land surface features and landscape patterns, hyperspectral imagery allows for the identification and characterization of materials. In addition to mapping the distribution of materials, an assessment of individual pixels is often useful for detecting unique objects in the scene.

Certain human proximity sensors utilize passive infrared sensing within the far infrared wavelength range to detect the presence of stationary[5] and/or moving human bodies.[6]

Different materials reflect and absorb differently at different wavelengths. As such, it is possible to differentiate among materials by their spectral reflectance signatures as observed in these remotely sensed images, whereas direct identification is usually not possible.

Hyperspectral vs multispectral

For these applications, ground truth signatures collected in the field and indexed in spectral libraries are critical for many methods of analysis. While image processing packages often include basic spectral libraries, application distinct libraries containing spectra of the specific materials occurring in the target field area greatly improves the accuracy of generated interpretations. Spectra of vegetation are influenced by such a wide range of environmental conditions that it makes it difficult to adequately represent this variability without the collection of site-specific field spectra.

Far infrared (FIR) or long wave refers to a specific range within the infrared spectrum of electromagnetic radiation. It encompasses radiation with wavelengths ranging from 15 μm (micrometers) to 1 mm, which corresponds to a frequency range of approximately 20 THz to 300 GHz. This places far infrared radiation within the CIE IR-B and IR-C bands.[1] The longer wavelengths of the FIR spectrum overlap with a range known as terahertz radiation.[2] Different sources may use different boundaries to define the far infrared range. For instance, astronomers often define it as wavelengths between 25 μm and 350 μm.[3] Infrared photons possess significantly lower energy than photons in the visible light spectrum, with tens to hundreds of times less energy.[4]

Objects within a temperature range of approximately 5 K to 340 K emit radiation in the far infrared range as a result of black-body radiation, in accordance with Wien's displacement law. This characteristic is utilized in the observation of interstellar gases, which are frequently associated with the formation of new stars.
