摘要：A single acoustic filter plate-lens unit for providing directional, frequency independent beam-forming. The unit comprises a liquid container having a curved and radially tapered stainless steel plate on one side and thin metallic shell on the other. An acoustically slow liquid fills the space between the plates. The unit can be used in conjunction with a retina transducer system for conversion of acoustic signals into electrical signals and vice versa.
