Abstract
This paper describes a technique where ultrasonic beam-modifying elements (acoustic lenses) have been designed in CAD, and then fabricated using rapid-prototyping techniques. An example of such a lens (resembling a miniature Schmidt-Cassegrain telescope) has been fabricated, and has been successfully used with a standard, commercially available ultrasonic transducer for imaging. Examples of images taken of a coin are given. Details of the design, build, performance and analysis of this focusing system are described.
