Paper Abstract

An object-localized reference mirror is used for the first time in an electronic speckle pattern interferometer (ESPI). This approach, together with the established technique of stroboscopic ESPI, is used to study the dynamic volume viscoelasticity of a submerged rubber sample undergoing sinusoidal vibration. These two modulation techniques allow manipulation of the fringe field describing the sample movement, helping to simplify data extraction.
