Description
нал, пропорциональный разности фаз генерируемых колебаний. Этот сигнал поступает на катушку обратной св зи 4, благодар чему обеспечиваетс синхронизаци частот сигналов квантовых датчиков-генераторов 1 и 2, при этом сила тока обратной св зи, регистрируема регистратором 5, устанавливаетс пропорциональной разности напр женностей магнитного пол в объемах квантовых датчиков-генераторов 1 и 2.nal proportional to the phase difference of the generated oscillations. This signal is fed to the feedback coil 4, which ensures synchronization of the frequencies of the signals of the quantum sensor generators 1 and 2, while the feedback current recorded by the recorder 5 is proportional to the difference of the magnetic field strengths in the volumes of the quantum sensors 1 and 2.
Благодар тому, что один из квантовых датчиков-генераторов 2 помещен внутрь электромагнитного экрана, приращени магнитного нол воздействуют только на один из них и на регистратор 5 поступает сигнал, йропорЦибнальный приращению напр женности магнитного пол в объеме, занимаемом квантовым датчиком-генератором 1.Due to the fact that one of the quantum sensor-generators 2 is placed inside the electromagnetic screen, the increments of the magnetic zero affect only one of them and the recorder 5 receives a signal, an irocorrant amplitude of the magnetic field in the volume occupied by the quantum sensor-generator 1.
Частотные характеристики устройства строго соответствуют частотным характеристикам экрана и могут регулироватьс путем подбора проводимости материала, числа слоев и толщины оболочек экрана.The frequency characteristics of the device strictly correspond to the frequency characteristics of the screen and can be adjusted by selecting the conductivity of the material, the number of layers and the thickness of the screen envelopes.
Таким образом, предлагаемое устройство благодар наличию электромагнитного экрана обеспечивает возможность измерени вариаций напр женности магнитного пол . Порог чувствительности при изглерени х в полосе частот, равной 1 Гц, может быть не хуже 1. }0-« Э.Thus, the proposed device, due to the presence of an electromagnetic shield, makes it possible to measure variations in the intensity of the magnetic field. The sensitivity threshold for glueing in a frequency band of 1 Hz can be no worse than 1.} 0- "E.
