    Title: Method and Apparatus for Measuring the Temperature of a 
Liquid Medium.
    Abstract: A method and apparatus for measuring the temperature of a 
liquid medium are disclosed. In accordance with the present invention, 
a liquid medium containing a fluorescent dye is provided. The 
fluorescent dye is chosen to exhibit a first fluorescence intensity at 
a first wavelength and a second fluorescence intensity at a second 
wavelength, wherein the temperature of the liquid medium may be 
determined in accordance with a predetermined temperature function of 
the first fluorescence intensity and the second fluorescence intensity. 
The method of the invention comprises the steps of measuring the 
fluorescence intensities at the first and second wavelengths; and 
determining the temperature of the liquid medium in accordance with the 
predetermined temperature function. The apparatus comprises means for 
measuring the first and second fluorescence intensities, and means for 
determining the temperature of the liquid medium in accordance with the 
predetermined temperature function. The apparatus preferably is a 
confocal optical measuring device, and preferably is capable of 
determining a temperature profile within the liquid medium.
