An Opto-Acoustic Transducer (OAT) is a multi-layer, planar device which produces a focused acoustic field distribution at its focal plane by transforming a pattern of optical intensity into a corresponding pattern of pressure amplitude. A typical OAT consists of four layers: a transparent electrode, a photoconductive layer, a piezoelectric layer, and an opaque electrode. One measure of the effectiveness of such a device as an acoustic transducer is the degree of resemblance of the acoustical output to the optical input.
