Far infrared - Wikipedia

Far infrared (FIR) is a region in the infrared spectrum of electromagnetic infrared is often defined as any radiation with a wavelength of 15 micrometers (μm) to 1 mm (corresponding to a range of about 20 THz to 300 GHz), which places far infrared radiation within the CIE IR-B and IR-C bands. The long-wave side of the FIR spectrum overlaps with so named terahertz radiation.

Thermal Infrared Sensor (TIRS) | Landsat Science

Historical note: Stray light from far out-of-field has affected the Landsat 8 Thermal Infrared Sensor (TIRS) absolute calibration since launch. An algorithm to correct for this issue was developed and implemented into the processing system in February 2017. A hardware solution to this problem has been implemented for Landsat 9’s TIRS-2.

Infrared - Wikipedia

Natural infrared. Sunlight, at an effective temperature of 5,780 kelvins (5,510 °C, 9,940 °F), is composed of near-thermal-spectrum radiation that is slightly more than half infrared. At zenith, sunlight provides an irradiance of just over 1 kilowatt per square meter at sea level. Of this energy, 527 watts is infrared radiation, 445 watts is visible light, and 32 watts is ultraviolet radiation.

Infrared photography - Wikipedia

In infrared photography, the film or image sensor used is sensitive to infrared light. The part of the spectrum used is referred to as near-infrared to distinguish it from far-infrared, which is the domain of thermal imaging. Wavelengths used for photography range from about 700 nm to about 900 nm. Film is usually sensitive to visible light too, so an infrared-passing filter is used; this lets ...

Improvement Technology for Far Infrared Sensors - Panasonic

Apr 16, 2021· By introducing this technology to a thermal-type far infrared sensor, heat loss from the infrared-receiving section was reduced approximately to 1/10 of the initial sensor without the phononic crystal structure. As a result, infrared detection sensitivity was improved nearly by a factor of 10 in the sensors with phononic crystals.

Thermal imaging uses cameras that “see” heat instead of light. Sometimes referred to as “FLIR” cameras, they produce an image that portrays objects using their temperature instead of their visible properties. So how does thermal imaging see heat?
