Abstract
A temperature sensor comprising a probe, infrared fibers, super-cooled detors and their associated electronics, and a computer for determining the temperature from the output of the electronics. Photons from a heat source are collected by the infrared fibers and transmitted to the detectors where they are amplified by the electronics. A voltage is then outputted which represents measured temperature. The voltage is sampled by the computer where it is converted to temperature by use of computer algorithms.
