発明の名称 (英語) RADIATION MEASUREMENT DEVICE
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.
特許請求の範囲(英語) [claim1]
1. An ultra-low temperature cryogenic vacuum to maintain the vacuum inside a constant temperature oven, for amplifying the radiation of the first frequency and the first optical path, said vacuum cryogenic black body and provided in a constant temperature tank, to amplify the radiation of the first and second frequencies and the second optical path, wherein the cryogenic vacuum provided outside of the thermostatic oven for separating the polarized radiation and the polarizing filter, the black body radiation from the polarizing filter is placed in the third optical path and, wherein the first optical path and said second optical path which has passed through the spectrum analyzer and analyzing the signal, which is composed of, said vacuum cryogenic in a constant temperature tank is a black body of, 10-4Pacryogenic vacuum of no more than 30K and a state of thermal equilibrium levels following LBlm, said polarizing filter is object when receiving a radiation, wherein the radiation of the object to be separated into light polarized by the polarizing filter, said first one of the separated XXXXnetwork into the optical path, the other is at the same time said second XXXXnetwork into the optical path, and, wherein said polarizing filter is a black body wherein the third optical path of the radiation through when receiving, the black body radiation is polarized by said polarizing filter are separated, the separated one of said first optical path is encased, the other is at the same time said second optical path into, wherein the first frequency of the radiation of the object in the first radiance of said polarizing filter said first optical path of said spectrum analyzer→→ .CZmU procedure, the first and second frequencies of the radiation of the object in the second radiance of said polarizing filter and the second optical path of said spectrum analyzer→The→ .CZmU procedure, wherein the black body radiation at a first frequency of the third radiance of said polarizing filter→→procedure of said first optical path measured by the spectrum analyzer, the black body radiation of the first and second frequencies of said fourth radiance of said polarizing filter and the second optical path of said spectrum analyzer→The→Tetralin procedures, each procedure according to the measured at said first and second radiance ratio of radiance, said third and fourth radiance using a ratio of the radiance of the light by calibrating, black body temperature of an object to be measured using the measurement value T2·Rs, furthermore, the temperature of an object that should be found (defined by the formulas PIanckian blackbody temperature of) T1and using the black body temperature of an object of the measurement value of the measured T2Δ T temperature error and (=T1-T2) is, the absolute temperature of the object t1used and t the absolute temperature of the black-body2temperature ratio and t1/t2becomes small in inverse proportion to the, used in the low-temperature blackbody temperature of the temperature increases above a certain value to reduce the error in effect is increased, the temperature of an object to be determined can be determined with high precision to radiation characterized in that the measuring device.
