Abstract

FIELD: applied magnetic optics, detectors of electromagnetic beams which use Faraday effect. SUBSTANCE: thermostatic unit 9 provides temperature which is slightly below one when layer of high- temperature superconductor 6 goes to superconducting state. In addition magnetic field which is generated by unit 10 is ejected from layer of superconductor 6. three-dimensional distribution of magnetic field at surface of layer 6 is detected by means of magneto-optical film 5. Light from source 1 runs through polarizer 2, light separator 3, substrate 4, film 5 and is reflected from border between film 5 and layer 6. After reflection light runs through film 5, substrate 4, light separator 3 and analyzer 7. When electromagnetic beam enters layer 6, latter is heated in this point and looses its superconductivity. This results in fact that magnetic field which is generated by unit 10 enters in layer of superconductor 6 in this local areas. This results in change of domain structure in film 5. EFFECT: increased functional capabilities. 1 dwg

Изобретение относится к области прикладной магнитооптики и может найти применение в датчиках и визуализаторах пучков электромагнитного излучения на базе элементов, использующих магнитооптический эффект Фарадея. С помощью термостатирующего блока 9 создают условия, при которых слой высокотемпературного сверхпроводника 6 находится при температуре, несколько меньшей температуры перехода в сверхпроводящее состояние. При этом магнитное поле, создаваемое блоком 10, выталкивается из слоя сверхпроводника 6. Пространственное распределение магнитного поля у поверхности слоя 6 регистрируется с помощью магнитооптической пленки 5. При этом свет от источника 1 проходит через поляризатор 2, светоделитель 3, подложку 4, пленку 5 и отражается от границы раздела пленки 5 со слоем 6. После отражения свет проходит пленку 5, подложку 4, светоделитель 3, анализатор 7. При попадании пучка электромагнитного излучения на слой 6 последний локально нагревается и частично теряет сверхпроводящие свойства. Магнитное поле, создаваемое блоком 10, в этих локальных участках проникает в слой сверхпроводника 6, что вызывает перестройку конфигурации визуализируемой доменной структуры в пленке 5.The invention relates to the field of applied magneto-optics and may find application in sensors and visualizers of electromagnetic radiation beams based on elements using the magneto-optical Faraday effect. Using a thermostatic unit 9 create the conditions under which the layer of high-temperature superconductor 6 is at a temperature slightly lower than the temperature of transition to the superconducting state. In this case, the magnetic field generated by block 10 is ejected from the superconductor layer 6. The spatial distribution of the magnetic field at the surface of layer 6 is detected using a magneto-optical film 5. In this case, light from the source 1 passes through polarizer 2, beam splitter 3, substrate 4, film 5 and it is reflected from the interface of the film 5 with the layer 6. After reflection, the light passes through the film 5, the substrate 4, the beam splitter 3, the analyzer 7. When a beam of electromagnetic radiation hits the layer 6, the latter is locally heated and partially loses light hprovodyaschie properties. The magnetic field generated by block 10, in these local areas penetrates the superconductor layer 6, which causes a restructuring of the configuration of the visualized domain structure in the film 5.
