Description
Изобретение относитс к Яaгнит ным измерени м и может быть исполь-. ,зовано дл измерени индукции импульсных и посто нных магнитных полей в соленоидах.The invention relates to magnetic measurements and can be used. It is designed to measure the induction of pulsed and permanent magnetic fields in solenoids.
Известны магнитооптические устрой ства , содержащие жесткую оптическую скамью, на которой- смонтированы ис- точник света, фокусирующа оптическа система, пол ризатор, датчик из материала, оптическа активность которого обусловлена магнитным полем, анализатор и фотодетектор l3.Magneto-optical devices are known that contain a rigid optical bench on which a light source, a focusing optical system, a polarizer, a sensor made of a material whose optical activity is caused by a magnetic field, an analyzer, and a photodetector l3 are mounted.
Однако такие устройства громоздки и неудобны в эксплуатации, им свойственна низка точность измерений, обусловленна разъюстировкой оптической системы при перемещении датчика в различные точки рабочего объема соленоида.However, such devices are cumbersome and inconvenient in operation, they are characterized by low measurement accuracy due to misalignment of the optical system when the sensor is moved to different points in the working volume of the solenoid.
Наиболее близким к предлагаемому по технической сущности вл етс магнитооптический зонд дч измерени магнитной индукции,, содержащий пол ризатор , датчик Фараде , анализатор, расположенные в едином узле входной и выходной световоды, причем указанные элементы магнитооптического зонда расположены в цилиндре из немагнитного материала 2.The closest to the proposed technical entity is a magneto-optical probe for measuring magnetic induction, containing a polarizer, a Farade sensor, an analyzer located in a single node of the input and output light guides, and these elements of the magneto-optical probe are located in a cylinder of nonmagnetic material 2.
Устройству также свойственна низка точность измерени , св занна с применением изогнутых световодов значительной длины. В немагнитной трубе в области расположени пол ризатора , датчика и световода возникают вихревые токи, создающие собственное магнитное поле, создающее дополнительные погретиности. Кроме The device also has a low measuring accuracy associated with the use of curved optical fibers of considerable length. In a nonmagnetic tube, eddy currents arise in the region of the polarizer, sensor and fiber, creating their own magnetic field, creating additional surface. Besides
10 того устройство невозможно использовать дл измерени импульсных полей в аксиальных системах с малым внутренним диаметром, поскольку измерительный зонд имеет большой диа15 метр.Moreover, the device cannot be used to measure pulsed fields in axial systems with a small internal diameter, since the measuring probe has a large diameter.
Цель изобретени - повышение точности измерений и расширение области применени .The purpose of the invention is to improve the measurement accuracy and expand the scope.
