Abstract
A new method is presented that allows continuous deformation measurements to be performed. It is based on the use of the deformation-induced phase change produced at each pixel to compute an instantaneous phase with a dedicated phase- shifting algorithm. Examples in holographic, speckle and decorrelated speckle interferometry illustrate the interest of the method which provides both relative displacement phase maps and absolute temporal phase evolution curves.
