ABSTRACT:
Optical temperature sensors use a temperature-dependent relative distribution of the intensity of interrogating light of wavelengths .lambda..sub.1 between two light-guiding regions of a light-guiding probe. The relative distribution can be determined by a plurality of means including the spatial separation of the lights carried by the two light-guiding regions, and/or the conversion of one of the lights into light of wavelengths .lambda..sub.2 different and easily separable from light of wavelength .lambda..sub.1. The sensors can be adapted to measure infrared radiation by measuring its heating effect on the sensing probes and to convert a thermal infrared image into a visible image.
