✦ Synopsis

We design a novel interferometer for the real-time wavefront measurement, which is based on the diffraction grating holography technique, where the diffraction gratings act as a beam splitter and a phase retarder, thus four interference patterns can be simultaneously obtained. Computer simulations show the validity of the approach and experimental setup is also presented.
