Abstract

A brief review of the application of acoustic speckle as an information carrier for uses is surveyed first. A two-dimension acoustic speckle pattern (ASP) as a whole is shown for the first time by liquid surface relief method, and the basic principle of taking ASP due to a random gridded-like "acoustic diffuser" is presented. Also, the use of ASP for measuring displacement of underwater object is given, and the physical linking of ASP and the sun glitter pattern on random sea waves is described as a possible new application of ASP.is described.
