【発明の詳細な説明】
この発明は塩化銀、臭沃化タリウムなどを用いて作られ

所の周囲の温度の影響の補正に関する。[Detailed Description of the Invention] This invention utilizes a fiber made of silver chloride, thallium bromoiodide, etc. that transmits long wavelength infrared rays, and the fiber passes through when measuring temperature in a low temperature range. Concerning the correction of the influence of the ambient temperature of the place.
塩化銀および奥沃化タリウムなどを用いて作られたファ
イバーは従来の石英を使用したファイバーに比較し、長
波長の赤外線を透過する。Fibers made from materials such as silver chloride and thallium iodide transmit longer wavelengths of infrared rays than conventional fibers made from quartz.

度とファイバーの透過波長帯域が重なる為、低温域の温
度計測に用いることが出来る。The peak value of the radiation intensity of the infrared rays emitted from the surface of a blackbody shifts to the longer wavelength side in the low temperature range, so it was impossible to measure the low temperature range with a conventional fiber-based thermometer. If a fiber that transmits long-wavelength infrared rays, such as silver or thallium bromoiodide, is used, the radiation intensity of a black body in the low temperature range overlaps with the transmission wavelength band of the fiber, so it can be used for temperature measurement in the low temperature range.

り得られた温度情報に影響を与える。In fiber type infrared radiation thermometry using this long wavelength transmission fiber, the difference between the temperature measurement area and the temperature of the surrounding area through which the fiber passes is small or nonexistent. Therefore, the temperature of the fiber itself changes under the influence of the temperature of the surroundings through which the fiber passes, and this temperature change of the fiber affects the temperature information obtained from the object to be measured.

。In order to correct this effect and obtain reliable temperature information, the present invention has a long-wavelength transmitting fiber t device with an optically closed end on the object side parallel to the fiber for measuring the object, and a temperature sensor on the opposite side. By placing a detector, information on the temperature of the surrounding area through which the fiber passes is obtained, and the temperature information obtained from the fiber on the measurement side of the object is corrected.

の温度情報がファイバーの周囲の温度となる。The long wavelength transmission fiber with the end on the object side optically closed, which is placed parallel to the long wavelength transmission fiber for measuring the object, has the same temperature as the long wavelength transmission fiber for measuring the object, and the optical Since the object side is closed, by placing a temperature detector on the opposite side of the object, temperature information can be obtained from the infrared rays emitted by the fiber itself, but this temperature information can be compared to the temperature around the fiber.

Since the long wavelength transmission fiber 5 provided for ambient temperature correction is optically closed by the section 2, only infrared light generated from the fiber itself is given to the temperature detector 7.

This has the effect of greatly expanding the range of measurement.
