Abstract
The disclosed invention concerns a process for the optical measurement of temperature, a probe device for the carrying out of the process, and a process for producing probe. The probe device contains a pellet of liquid crystals which is contained within an envelope and arranged at the end of an optical fiber. The optical fiber receives light, which is continuously swept by different wavelengths and the light reflected by the liquid crystal is analyzed to detect the reflection peaks and deduce the probe temperature.
