Application of refraction and diffraction of light to the measurement of the liquid surface shape deformed by ultrasonic radiation pressure

A method of measuring the liquid surface (hump) deformed by ultrasonic radiation pressure is proposed. The method is based on the usage of a hump as a liquid lens with an interference structure formed by sound waves falling on the surface. The hump shape is evaluated by means of shadowgrams obtained...

Description
Summary:A method of measuring the liquid surface (hump) deformed by ultrasonic radiation pressure is proposed. The method is based on the usage of a hump as a liquid lens with an interference structure formed by sound waves falling on the surface. The hump shape is evaluated by means of shadowgrams obtained with laser illumination. The possibility of using the hump as a sensor of processes occuring in the liquid through which sound waves are passing is shown.
