Abstract :
The optic-fiber temperature measurement probe based on ruby is developed. This system is particularly adapt to the temperature measurement in the rang of 0°C to 130. The calibration graph was shown to be highly reproducible when the probe is temperature cycled. A change in drive current from 5 to 30mA yields a spectral shift of the peak emission of only a few nanometers. The drive current to the LED can easily be kept within the required narrowly defined bounds through the control circuitry.
