Abstract
Interference holography with a pulsed ruby laser is used for analyzing the vibration pattern of an acoustic source. In our experiments the pattern was composed of two different vibrational modes. The pattern pertaining to a single mode can be obtained from the interpretation of a set of two holographic interferograms, taken under electronically controlled conditions. The interpretation methods that have been used were a moire-technique and an automated digital technique. Applications of these techniques in a few cases are discussed, and the effect of small timing errors in the electronic system on the results is determined.
