Abstract

Optical interferometric techniques are being increasingly used in laboratory test and can usefully substitute other classical techniques when great accuracy in measuring displacement is required. In particular, Electronic Speckle Pattern Interferometry (ESPI) technique has aroused lively interest by the industrial and research users because does not require excessive environmental stability and does not necessary photo processing. In the paper the authors show the results obtained applying the ESPI methods to mechanical characterization of clay materials used to manufacture blocks for composite floors.
