What is Radiometry ?

Radiometry Definition

Radiometry is defined as the technique of measuring electromagnetic radiation across all wavelengths, including ultraviolet, infrared, and visible light.

Radiant Energy

Radiant Energy (Qe) is the energy carried by electromagnetic radiation, while Radiant Flux (ф) is the radiant energy transmitted per unit time.

Microwave Radiometry

Microwave radiometry is a method to measure the thermally caused electromagnetic radiation from matter above zero Kelvin, using antennas and detectors.

Brightness Temperature

The radiation received by a microwave radiometer is expressed as brightness temperature, which is almost weather independent.

Photothermal Radiometry

Photothermal radiometry is a technique that uses optical excitation to produce thermal waves and radiometric detection to measure IR radiation, crucial for material inspection without contact.
