Plasma spraying is widely used for coating deposition and advanced material forming. To control the plasma spraying process, one should be able to evaluate on line the key physical process variables, including the bulk temperature of particles (Pfender and Chang, 1998; Moreau, 1998; Fincke et al., 2001; Fauchais, 2004; Fauchais et al., 2006; Streibl et al., 2006). The particle temperature is usually determined experimentally from the ratio of the thermal radiation detected at two closely related wavelengths (two-color pyrometry). As a result, the so-called color temperature is obtained. It the case of a semitransparent particle, the color temperature is int ...
