Phase measurement using high-speed movable stage by digital holography under CW laser illumination

Fast measurement system of a moving three-dimensional phase object using digital holographic microscopy is presented. In the fabricated system, a three-dimensional phase object is put on a fast movable stage. Under the CW laser illumination, the holograms of the phase object are superimposed. We experimentally investigated the effect of the speed of the movable stage on the reconstructed data.
