Abstract
PURPOSE:To perform temperature measurement in a low temperature range simply and accurately by utilizing the fact that the transmittivity of crystalline optical fiber to ultraviolet and visible rays depends on temperature. CONSTITUTION:Crystalline optical fiber is set at a position where temperature is to be measured and ultraviolet and visible rays are passed through it. The temperature is measured by transmittivity of the rays. For instance, a crystalline optical fiber 1 in which the core is AgCl (100%) and the clad is AgCl (92%)-AgBr (7%) is wound round a part 2 to be measured. Light of 0.42 micron in wavelength is passed to this from a laser emitter 3 and the transmittivity is measured with a light receiver 4 consisting of a photoelectric multiplier. In this case, for instance, transmittivity of 0, 6.2 and 81% are obtained at 198K, 89K and 3K respectively, and thus an accurate temperature measurement is made possible over a wide range in a low temperature range. Crystals of various halogenides can be used as material for optical fiber.
