Phase retrieval is a simple and concise way of reconstructing wavefront, especially the method based on single far field formed by just a lens. However, for the symmetry of Zernike polynomial aberrations, light with different wavefront could form the same far-field intensity distribution. The distribution of reconstructed wavefront is likely to be quite different from the real one. In other words, it suffers in the multi-solution problem. A kind of wavefront reconstruction method based on quadrant binary phase plate is proposed. Incident light is modulated by a first-order Modified-Walshfunction pattern quadrant binary phase mask, which violates the special symmetries. Simulation experiments show that this method can retrieval random wavefront distributions accurately. It provides a practical technical solution for precise wavefront sensing with single far field image.
