Holographic techniques were shown to be very informative about the steady-state vibrational behavior of transducers. Holograms of objects vibrating underwater were successful but, more developmental work is needed before high quality results can be obtained. Real time fringes were shown to be very useful in the laboratory for finding transducer resonances the time average hologram then gives detailed results. They hold promise for studying transient effects. Another promising application of our holographic studies follows directly from the Directionally Sensitive Membrane Employing Optical Diffraction. This would be a stretched membrane or a very thin clamped plate for which real time fringes are produced. Any sound wave striking the plate would disturb the real time fringes. Very minute pressure disturbances could be detected. Author
