    Abstract

    An optical facility is described for the study of the vibrational behavior of engineering test pieces. Time-average holography
    and electronic speckle pattern methods of analysis are combined into one system. The speckle pattern method is used for the identification
    of resonances, frequency tuning, and object alignment, thereby optimizing the number of holographic exposures. An evaluation is
    made of the electronic speckle pattern method for the detection of vibration modes of three-dimensional objects. The method is shown
    to detect resonant vibration readily on object faces inclined at angles up to 60° to the viewing direction.
