Application of holographic interferometry for the investigation of ultrasonic fields
Abstract
An ultrasonic beam impinging at a free-liquid surface produces a bulge caused by the radiation pressure. Neglecting the surface tension effect of the transmission medium, the local height of the surface relief is proportional to the local acoustic intensity. With the aid of holographic interferometry, this relief is rendered visible and quantitatively evaluated.
