Remote Measurement of Fluid Temperature.
Abstract
This patent application pretains to the remote temperature measurement of a fluid which is determined by Raman backscattered radiation from the fluid where the fluid is subjected to intense pulses of laser radiation generated at a remote location. The backscattered radiation is filtered to selectively attenuate reflected radiation from the laser and is transmitted to a detector system which individually counts the detected radiation in each of two different radiated frequencies. A divider generates a ratio of the count which is transformed by a function generator to produce an output signal indicative of fluid temperature.
