Description
Известен способ градуировки ультразвуковых щупов, меньших длины з.льтразвуковой волны, в ультразвуковых пол х, путем измерени оптическим методом разности хода световых лучей, вносимой ультразвуковым полем.There is a method of calibrating ultrasonic probes shorter than the length of an ultrasonic wave in ultrasonic fields by measuring the optical path difference of light beams introduced by an ultrasonic field using an optical method.
Оптические методы измерени разности хода световых лучей, вносимой ультразвуковым полем, основываютс на одном из трех влений: или на диффракции света на ультразвуке (метод диффракционных снектров), или на отклонении световых лучей на градиенте показател преломлени , создаваемого ультразвуком, или смещением интерференционных полос при изменении показател преломлени , вызываемого ультразвуком, в одном из плеч интерферометра.Optical methods for measuring the difference in the course of light rays introduced by an ultrasonic field are based on one of three phenomena: either on the diffraction of light by ultrasound (using diffraction spectrums), or on the deflection of light rays on the gradient of the refractive index produced by ultrasound, or by shifting the interference bands when the index of refraction caused by ultrasound in one of the arms of the interferometer.
Однако указанный способ при наличии изменени амплитуды и фазы давлени вдоль пути (например, при высоких частотах) не дает возможности определить давление в любой точке ультразвукового пол , а позвол ет получать лишь декоторое усредненное значение его.However, this method, in the presence of a change in the amplitude and phase of pressure along the path (for example, at high frequencies), makes it impossible to determine the pressure at any point of the ultrasonic field, but only allows decoding its average value.
В предлагаемом способе зтот недостаток устран етс .In the proposed method, this disadvantage is eliminated.
Это достигаетс тем, что с помощью ультразвукового щупа определ ют функцию распределени амплитуды и фазы напр жени , снимаемого с указанного щупа, при движении его вдоль пути светового луча в ультразвуковом поле.This is achieved by using the ultrasound probe to determine the distribution function of the amplitude and phase of the voltage taken from the specified probe as it moves along the path of the light beam in the ultrasonic field.
