Modelling of optical fibre temperature sensors using blackbody radiation

摘要

The subject of this paper is the modelling of optical fibre temperature sensors that use blackbody radiation. The aim of modelling is in the optimum selection of optical filters - in order to obtain the highest possible sensitivity in the assumed range of temperature measurements. Modelling takes into account the influence of the transmittance of optical fibres, the spectral sensitivity of photo detectors and the filters characteristics on the photodetector signal level.
