Resumen:
The use of an electro-optic crystal as phase-stepping device in a digital speckle interferometer is discussed. Phase stepping is introduced by varying the external voltage applied to the crystal. The crystal calibration procedure is outlined and errors are discussed. Experimental results compared to those obtained with a piezo-electrically driven mirror are presented.
