Abstract
An acoustic device and related method for measuring the shape of an object. The device includes a plurality of transmitters for transmitting acoustic waves at an object to be measured and a plurality receivers for receiving the acoustic waves reflected by the object. A phase detector measures phase data of the reflected acoustic waves, the phase data being processed to calculate a value representing a shape of the object as a function of the phase data. This value is then compared with known reference value to accurately identify the shape of the object.
