- Instrument Introduction
The Electronic Speckle Interferometry (ESPI) experimental system utilizes speckles—carriers of information about rough surfaces—to study out-of-plane deformation of objects. It is a modern optical measurement technique that combines computer image processing, laser technology, and holographic interferometry. The high coherence of the laser makes the speckle phenomenon clearly visible, and the use of a CCD camera enables computer-based data and image processing. Electronic speckle interferometry has a wide range of applications, such as object deformation measurement, non-destructive testing, and vibration measurement.
