Abstract

One of the critical questions regarding radiation thermometers is how to obtain the true temperature of an emitting greybody with an unknown emissivity and with unknown circumferential radiations. In this paper it is suggested that two enclosed chambers with given temperatures and emissivities be used to cover part of the area of the greybody. By using two simultaneous radiothermometer readings, both the true temperature and the emissivity of the greybody can be calculated.
