Interferometric measurement system with a single illumination detection configuration for online full-field measurement of 3D object shifts

摘要

Device and method in the field of optical measurement technology for the contactless optical detection of displacement components of an observed object with the aid of a digital speckle pattern interferometer (DSPI), which is based on the “spatial carrier phase shifting” technique and in which the “adjustable Aperture Mixing "technology (AAM) is used.
