N2 - Plastic hollow waveguides were used for non-contacting temperature measurements. Employing these fibres, we performed temperature measurements between room temperature and 120°C, achieving good agreement with theoretically expected values. The temperature and spatial resolutions of the waveguides were measured. The temperature resolution was found to be 0.08°C (fibre dimensions: internal diameter 2.4mm, length 60 cm) and the spatial resolution was approximately equal to the inner diameter (ID) of the waveguide. The curvature loss of the waveguide increased with decreasing radii of curvature. It was shown that waveguides with dielectric layer thicknesses of 0.2-0.6 μm are suitable for radiometry at this temperature range.
