Paper Abstract

The principle of Electronic Speckle Pattern Interferometry - ESPI - is explained by comparing it to image holography where recording and reconstruction are performed by videotechniques. As such, ESPI can be used for different interferometric measurements, but it is especially suitable for vibration testing and measurement of movements. Our work on extending the measuring range and general use of ESPI for those purposes is described and illustrated by some practical applications.
