Electronic Speckle Pattern Interferometry (ESPI) has been developed to make possible to observe dynamic feature of deformation in Dynamic ESPI (DESPI). In DESPI for phase analysis, conventional phase shifting method cannot be applied. We have proposed alternative method, subtraction and addition method in which phase variation may be deduced only by sequential speckle data without any additional data. In this paper, DESPI is applied to measure entire process of tensile experiment of an aluminum alloy sample. Propagation of strain localized band was clearly analyzed. Accuracy of phase analysis is estimated to be about 2π/10.
