Abstract:

Expressions have been derived for spectra of scattering for scattering of the incoherent kind. These expressions contain temperature as a parameter, which could in principle be determined by making suitable measurements on the spectrum of scattering. The importance of accuracy in such measurements becomes clear, if it is realized that if the measurement of the width of the spectrum is in error by a factor F, the deduced value of temperature will be in error by the factor F2, the width of the spectrum being proportional only to the square root of the temperature. All predictions made so far for the spectra are based on the assumption that a sine wave is transmitted and that the received signal is observed continuously. The effects of pulsing the transmitter an gating the receiver are discussed. In most temperature measurements these effects should clearly be taken into account. Even in cases where this is not necessary, the measurement of temperature is not a trivial matter. The measurement of temperature in such cases is discussed in detail. Author
