Abstract: Phase retrieval using single farfield image data is the key to many applications. However, this method easily falls into stagnation because of the multiple solutions. A wavefront reconstruction algorithm based on the hybrid focal lengths Fresnel zone plane is proposed in this paper. By using the proposed method the partially focused and defocused information of wavefront can be captured on just one farfield image. This method can effectively solve the phase ambiguity, and the optical structure is very simple and easy to implement. Simulation results show that the proposed method can reconstruct wavefront aberration very precisely with just one far field.
