Measurement of vibrational energy flow using Electronic Speckle Pattern Interferometry

posted on 2018-10-26, 16:25 authored by Thomas Eck
Vibrational energy flow (VEF) analysis (VEFA) is used to attain vibrational energy flow information within a vibrating structure of interest. Two essential pieces of information are provided, the direction of the energy flow as well as the magnitude of the energy flow. Once this information is available, vibration may be manipulated in order to suppress undesired vibrational phenomena. The measurement of VEF is an important part in providing VEF information from real structures. In the past the measurement of VEF was restricted to single point measurements only. However, recent developments in advanced laser measurement techniques, such as electronic speckle pattern interferometry (ESPI), have gained interest in applying these measurement techniques to the measurement of VEF.
