ABSTRACT:
Remote measurement of temperature variations within polymer process melts is performed by irradiating the melt with a collimated radiation source such as laser light and relating the transmitted radiation to the temperature distribution within the melt. A method and apparatus for temperature profile determination is based upon the variation of light transmittance through the melt as a function of temperature and wavelength of the incident light.
