Abstract

A number of experiments in vibration analysis are discussed where different methods like hologram interferometry, impact testing, acoustical recording, FEM-calculations are compared to results obtained by means of an instrument based on image-plane, time-average hologram recording on a TV-vidicon like ESPI (electronic speckle pattern interferometry). The instrument, "VibraVision", offers distinct advantages in vibration studies.
