In the field of optical imaging, the image registration method could be applied to realize a large field of view along with high resolution. The traditional image registration methods are mostly conceived for intensity images and might fail for complex-valued images. Especially, those methods do not account for the random phase offset associated with phase. In this paper, we proposed a general method for complex-wave field registration. A similar procedure has been proposed for the reconstruction of the ptychographic dataset, but here is modified for the registration of general wave fields. The method can efficiently separate the illumination and object function, refine the positions of each wavefront, and thus provide a stitched wide-field object wave with high fidelity. Simulation and experimental results applied to register the wave fields obtained from digital holographic microscopy are given to verify the feasibility of the method. This method would have potential applications in large-field high-resolution microscopy, adaptive imaging, remote sensing and the measurement of structured optical fields.
