A kind of fluorescence optic-fiber thermometer is devised based on the ruby and absorbing glass sample. The optic- fiber temperature measurement probe based on ruby is developed. This system is particularly adaptable to the temperature measurement in the range of 0℃ to 130℃. A considerably improved performance is seen in this new device. The drive current to the LED can be easily kept within the required defined bounds through the control circuitry.
