Abstract : A new area for the application of holographic techniques has been investigated. A point source radiator located on the two-dimensional plane formed by an air-water interface was imaged using holography. A schlieren photograph was taken of the surface pattern produced by a radiating point source of capillary waves on water. Temporal reference line holograms were removed from the photographed pattern using a slit-shaped mask. Reconstructed images were formed in the converging beam of a helium-neon laser. The images were observed on a vidicon screen through a closed circuit television monitor. A theoretical study of capillary waves was made and some experiments were conducted in the generation and observation of these waves. Some suggestions are made to apply this new development to two-dimensional wave structures. (Author)
