Underwater Viewing System Using Sound Holography

Abstract

A feasibility study and prototype system development for an underwater viewing system based on acoustic holographic principles was initiated. The objective was to study various receiving array configurations and construct a modular prototype system to evaluate the capabilities of holographic concepts. In parallel, the development of a system for real-time optical reconstruction of sampled holograms was initiated. The report presents a summary of the program activities from its inception in 1968 to its completion in 1971. Accomplishments include completion of the design and construction of the underwater viewing system as well as that for the coherent light area modulator. Experimental verification of the system's operational capabilities was also completed. This includes the generation of holograms using the underwater viewing system and various target configurations, and the reconstruction of these holograms using the coherent light area modulator.
