発明の名称 (英語) RADIATION MEASUREMENT DEVICE UPDATE
発明の概要(英語) [Problem] The purpose of the present invention is to provide a radiation measurement device for measuring the temperature of an object with high precision.
[Solution] In the present invention: radiation from an object is separated into polarized light by a polarized-light filter (3); one portion of the polarized light is introduced into a spectrum analyzer (7) via a first optical path, the other portion of the polarized light is introduced into the spectrum analyzer (7) via a second optical path, and the dichroic ratio of the radiation is measured; radiation from a black body (2), which has been placed within a vacuum-cryogenic-temperature vessel (1) in a state of quasi-thermal equilibrium at a vacuum cryogenic temperature, is introduced into the polarized-light filter (3) through a third optical path and separated into polarized light; the resulting polarized light is introduced into the same optical paths as those for the portions of polarized light from the object and then introduced into the spectrum analyzer (7), and the dichroic ratios are measured; and the temperature of the object is determined with high precision from these two dichroic ratios.
従来技術、競合技術の概要(英語) BACKGROUND ART
Radiation in a non-contact measurement of the temperature as a method and device, for example, Non-Patent Document 1 and Patent Document 1-4 is known.
Patent Document 1 is, radiation from the emitter 2 is directed to a one polarization component, the spectral radiance L1 and L2 as well as measures, the off-line and the back light without being measured at each polarization component of the emissivity ε1t and ε2t are used to compensate for the effects of light by the back, the method of determining the temperature of the radiator is disclosed.
Patent Document 2 is, the infrared radiation from the radiation transmitted through the infrared filter, subsequently, by the second polarizer 1 are polarized, subsequently polarized light 2 by means of a electro-optical radiation the two orthogonal polarized components and at the same time the harmonic amplitude modulation, the harmonic amplitude ratio and the numerical analyzer calibration look-up table prepared in advance and the temperature can be obtained from the disclosure.
Patent Document 3 is, under an environment with a comb generator may be a cryo, the black body and the cooling of a black body at room temperature (liquid nitrogen and exposed to a black body) and are disposed so as to face each other, can be calibrated on the temperature of the microwave - diones. Under an environment of a black body about how cryo not mentioned.
Patent Document 4 is, the black body and the cooling of a black body at room temperature (the black body is dipped into liquid nitrogen) are separately prepared, can be calibrated on the temperature of the microwave - diones.
Non-Patent Document 1 is, the black body and the cooling of a black body at room temperature (the black body is dipped into liquid nitrogen) is prepared, and each of the radiation emitted from the chopper wheel of a very low temperature or at room temperature through the mixer pre-amplifier into the detector, radiation temperature measurement is disclosed.
However, the method of the above, the influence of disturbance of the measurement of radiation directly to the external environment while being indirectly since the method, the black body is always normal temperature region and temperature variations, liquid nitrogen cooling black body thermal radiation that the boiling point of 77K is because a disturbance of the vibration or heat, the temperature of the radiator can be measured with high accuracy is a problem that it is difficult.
