Temperature Measurement of Transparent Solid Bodies
Pyrometric, Contactless Method
All solid bodies which partially or totally transmit thermal radiation in the wavelength of visible and infrared radiation, are classified as transparent bodies . The notation used to consider pyrometric methods for measuring the surface temperature of solid bodies has already been introduced in Section 8.2. It will be recalled that solid bodies, which have a transmission factor limited to a = 0, are non-transparent bodies in the whole range of wavelengths used in optical pyrometry . The same notation will be used in this chapter....
