Изобретение относитс к акустоэлектронике , в частности к приборам и устройствам, основанным на взаимодействии ультразвуковых (УЗ) волн с носител ми зар да в твердых телах/ и может быть использовано дл обнаружени и детектировани УЗ волн, распростран нидихс в жидкост х, либо твердых телах.The invention relates to acoustoelectronics, in particular, to devices and devices based on the interaction of ultrasonic (US) waves with charge carriers in solids / and can be used to detect and detect ultrasonic waves, propagating fluids in liquids or solids.
Известен ультразвуковой преобразователь , содержащий корпус с размещенным в нем активным элементом в виде кристалла пьезоэлектрика, нижн акустическа грань которого металлизирована, а на верхнюю с заданной дискретностью нанесены металлические контакты l . iA ultrasonic transducer is known, comprising a housing with an active element in the form of a piezoelectric crystal, the lower acoustic face of which is metallized, and metal contacts l are applied to the upper one with a given discreteness. i
Однако существенным недостатком такого преобразовател вл етс низка чувствительность, узкополосность, нелинейна зависимость от мс дности падак цей ультразвуковой волны что. во многих случа х ограничивает функциональные возможности контрол такого устройства.However, a significant drawback of such a transducer is the low sensitivity, narrowband, non-linear dependence on the MS of the ultrasonic wave that. in many cases, it limits the control functionality of such a device.
Известен также акустоэлектрический преобразователь ультразвука, соержащий корпус и расположенный в ем пьезополупроводниковый кристалл с потенциальными электродами f23 .An acoustoelectric ultrasound transducer is also known, which encloses the body and a piezo-semiconductor crystal located in it with potential electrodes f23.
Однако такой акустоэлектрический преобразователь не позвол ет проводить локальные измерени ультразвукокового пол и, соответственно, его пространственного распределени .However, such an acoustoelectric transducer does not allow local measurements of the ultrasound field and, accordingly, its spatial distribution.
Дл измерени пространственного распределени ультразвукового пол кристалл имеет форму пластины, на одной стороне которой нанесены с заданной дискретностью потенциальные электроды в виде узких металлических полосок.To measure the spatial distribution of the ultrasonic field, the crystal is plate-shaped, on one side of which potential electrodes in the form of narrow metal strips are deposited with a given discreteness.
На чертеже изображена конструкци предлагаемого преобразовател .The drawing shows the structure of the proposed converter.
Он состоит из кристалла 1 пьезополупроводника , помещенного в корпус 2, Одна из граней кристалла плоскополирована, а на противоположную методом напылени в вакуума нанесены металлические электроды 3 соединенные с помощью проводников 4 со штеккерным разъемом 5. Торцова акустическа . поверхность кристалла 1 защищена тонкой кварцевой пластиной 6. Дл придани системе достаточной жесткости внутренн полость устройства заполнена, например , эпоксидной смолой.It consists of a piezo-semiconductor crystal 1 placed in the housing 2, one of the crystal faces is flat-polished, and metal electrodes 3 connected by means of conductors 4 with a plug connector 5 are applied by vacuum deposition into a vacuum. The surface of the crystal 1 is protected by a thin quartz plate 6. To impart sufficient rigidity to the system, the internal cavity of the device is filled, for example, with epoxy resin.
В основе предлагаемого устройства использовано новое вление - поThe basis of the proposed device used a new phenomenon - by
