Abstract

This paper presents a study of speckle effects in measurements of static and vibratory displacements by digital holography. Such effects are shown to arise from changes in speckle fields that often occur between holographic recordings. These may be between recording holograms before and after static deformations or changes in sets of holograms recorded for vibration measurement. If the images do not change between such recordings, the effects appear to be limited mainly to round-off errors.
