Abstract
A new technique of multicolour radiation pyrometry is described. The directional emissivity of the surface whose temperature is being sought is estimated from measurement of the surface reflectance factor. Temperature measurements of a tungsten strip lamp in the range 1180-1680K using this technique agree within 0.3% with those obtained from its spectral radiance temperature and published emissivity data of tungsten.Keywords
