Liquid Surface Holography

  • Byron B. Brenden


As an acoustical hologram detector, the liquid surface has the distinct advantage that no scanning process is required. The interaction of two acoustical waves at a liquid surface occurs uniformly over a period of approximately 100 microseconds and produces deformations on the liquid surface that are capable of holographically reconstructing an optical wave equivalent to one of the two acoustical waves. The process may be repeated at the rate of sufficient to produce nearly 200 holograms and images per second. This is a sufficiently high rate of hologram production to allow as many as ten different frequencies to be used with the images of each frequency occurring rapidly enough to exceed the critical fusion frequency of the eye.
