Sažetak
Time-averaged digital holographic interferometry is already a well-established technique for studying vibration properties of objects. In this presentation, first the main properties such as the general expressions, stochastic fluctuations, sensitivity, and advantages as well as drawbacks of the technique are summarized. Then, for illustration, the following recent applications are presented: (i) detection of hidden stationary deformations, (ii) dynamic modal characterization of musical instruments, (iii) recording of large objects: hard disk deformations, (iv) chin rest influence on the vibration properties of the violin body, and (v) real-time monitoring of vibration-fringe patterns. Finally, some perspectives of the time-averaged digital holographic interferometry technique are discussed in relation to the improvements of the addressable devices and real-time applications.
