Abstract
The Spot Radiometer is a non-imaging, infrared instrument designed to measure either the temperature of a well-defined surface area or the radiosity from that area. (Radiosity is defined as the total radiation which leaves a surface per unit time per unit area, and is the sum of emitted and reflected radiation.) Typically, the Spot Radiometer is a portable, battery-operated device consisting of a collecting lens or mirror, an infrared detector, an amplifier, signal processor circuitry, and an analog or digital display.
