Abstract
Optical temperature sensors use a temperature-dependent relative distribution of the intensity of interrogating light 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 different easily separable from the wavelength or wavelengths of the interrogating light. The sensors can be adapted to measure infrared radiation by measuring its heating effect on the sensing probes to convert a thermal infrared image into a visible image.
