Abstract

A holographic lens for sound waves has been constructed and its imaging properties investigated theoretically and experimentally. First we discuss the advantages of holographic lenses over both conventional lenses and phased arrays. Then we use the techniques described in a separate paper for a theoretical study of the image quality and diffraction efficiency of the holographic lens. Finally, we compare the theoretical results with those obtained in a water tank experiment.
