Abstract
This paper shows that the electronic speckle pattern interferometry (ESPI) using large capacity image memory makes possible to measure the large deformation distribution of a rough surface object precisely. A simple experiment to measure the large deformation of a cantilever which cannot be measured by a conventional ESPI is performed and its analysis shows the measurement error is small.
