СПОСОБ ИЗМЕРЕНИЯ ТЕМПЕРАТУРЫ ТЕЛ ПО ИХ РАДИОЗа влено 9 декабр  1961 г. за 754899/26-10METHOD OF MEASURING TEMPERATURES OF BODIES BY THEIR RADIOSIS 9 December 1961 for 754899 / 26-10

в Комитет по делам изобретений и открытий при Совете Министров СССР Опубликовано в «Бюллетене изобретений № 17 за 1962 г.to the Committee on Inventions and Discoveries at the Council of Ministers of the USSR Published in «Bulletin of inventions No. 17, 1962

Изобретение относитс  к способам измерени  температуры тел по их радиоизлучению. Однако с помощью известных способов не удаетс  определ ть истинную температуру «нечерных тел за счет отличи  коэффициента черноты объектов измерени  от единицы. Определ ть отдельно коэффициент черноты в некоторых случа х невозможно, особенно когда в процессе измерени  температуры он быстро мен етс  или непосто нен по поверхности объекта.The invention relates to methods for measuring the temperature of bodies by their radio emission. However, using the known methods, it is not possible to determine the true temperature of the non-black bodies due to the difference in the blackness coefficient of the measurement objects from the unit. Separately, the coefficient of blackness is impossible in some cases, especially when in the process of measuring temperature it changes rapidly or is not constant along the surface of the object.

Предложенный способ измерени  температуры тел по их радиоизлучению обеспечивает определение истинной температуры «нечерных тел за счет их дополнительного облучени  от эталонного источника радиоизлучени  и замера радиометром суммарного собственного и отраженного излучени .The proposed method for measuring the temperature of bodies by their radio emission provides the determination of the true temperature of the non-blacken bodies due to their additional irradiation from a reference source of radio emission and measurement by the radiometer of the total natural and reflected radiation.

На чертеже изображена схема устройства дл  осуществлени  предложенного способа измерени  температуры тел по их радиоизлучению.The drawing shows a diagram of an apparatus for carrying out the proposed method for measuring the temperature of bodies by their radio emission.

При измерении температуры объект / облучаетс  от эталонного источника 2 радиоизлучений через приемную антенну 5 радиометра 4. Эталонный источник 2 подключен к Я-входу волноводного двойного Г-моста.When measuring the temperature of an object / irradiated from a reference source of radio emission 2 through the receiving antenna 5 of the radiometer 4. The reference source 2 is connected to the I-input of the waveguide dual G-bridge.

Подаваемое на Я-вход высокочастотное излучение делитс  поровну и поступает в плечи Л и В, в плечо же Е непосредственно из плеча Я оно не поступает. Обознача  поступающую от эталонного излучател  мощность 4Р , найдем, что в антенну поступает мощность 2Р,, .The high-frequency radiation fed to the I-input is divided equally and enters the shoulders of A and B, but it does not enter the shoulder E directly from the shoulder of I. Designating the 4P power coming from the reference radiator, we find that the antenna receives 2P ,, power.

На вход // радиометра поступает также мощность 2Р,, , но через, аттенюатор Л у она понижаетс  до Р,,. ИЗЛУЧЕНИЮThe power 2P ,, also arrives at the radiometer input //, but through the attenuator L y it decreases to P ,,. RADIATION

Отраженное от объекта измерение в результате его «нечерноты излучени  будет равно по мощности (. ) 2Рз . Эта мощность вместе с собственным излучением тела е изл поступает на второе плечо В обратно в двойной Г-образный мост.The measurement reflected from the object as a result of its "non-blackeness of radiation will be equal in power (.) 2Рз. This power, together with the body's own radiation e, is fed to the second shoulder B back to the double L-shaped bridge.

Так как поступающа  таким образом энерги  делитс  пополам между плечами Я и Е, не переход  к плечу А, половина этой энергии попадает в эталонный излучатель и там поглощаетс , а втора  половина проходит к входу / радиометра. Таким образом, радиометр 4 сравнивает мощности РЭ и - s. Pj;,j -f РЭ( - .v) При установке выходногоSince the energy thus received is divided in half between the shoulders I and E, not the transition to arm A, half of this energy falls into the reference emitter and is absorbed there, and the second half passes to the input of the radiometer. Thus, radiometer 4 compares the power of the OM and - s. Pj;, j -f РЭ (- .v) When setting the output

так как Р - КТ, Af и Р„з, ЛТ Af , но от эталонного излучател as Р - КТ, Af and Р „з, ЛТ Af, but from the reference radiator

беретс  мощность 4Р, , т. е. эквивалентна  температура эталонного излучател  должна быть Г,, 4Г% 27a power of 4P is taken, i.e. the temperature of the reference radiator must be equivalent to T ,, 4Г% 27

Предмет изобретени Subject invention

Способ измерени  температуры тел по их радиоизлучению, отличающийс  тем, что, с целью определени  истинной температуры «нечерных тел, их дополнительно облучают от эталонного источника радиоизлучени  и замер ют с помощью радиометра суммарное собственное и отраженное излучение.A method of measuring the temperature of bodies by their radio emission, characterized in that, in order to determine the true temperature of non-black bodies, they are additionally irradiated from a reference source of radio emission and their total and reflected radiation is measured with a radiometer.
