Abstract
A mechanism and method for directly observing data from which the thermal emissivity or absorptivity of a surface can be calculated. The invention teaches the use of a substantially planar heat-flux or heat-flow sensor employing a thermopile, to measure the rate of heat dissipation from a radiating surface thermally attached to one side of the heat-flux sensor where the radiating surface is exposed to a first temperature and where the second side of the heat flux sensor is in thermal contact with a heat source at a second higher temperature.
