Two-step quadrature phase-shifting digital holography based on the calculated intensity of a reference wave is proposed. In Mach-Zehnder interferometer (MZI) architecture, method only records two quadrature-phase holograms, without reference-wave or object-wave measurement, to perform object recoding and reconstruction. When from 2D correlation coefficient (CC) that we presented, clear reconstruction image can be obtained by some specific algorithm. Its feasibility validity were verified series experiments with objects 3D objects. The presented will widely used in real-time dynamic applications.
