Abstract
To avoid the problem that traditional Gerchberg-Saxton ( GS ) algorithm was easy to get into a partial extremum and could not achieve the desired accuracy , a simple circulatory GS algorithm was used by increasing the amount of information, in another words , increasing one plane so that the GS algorithm could get out of the partial extremum effectively.After the simulative calculation, the phase and amplitude distribution of pupil plane was recovered by the intensity information of the focal plane or nearby position although the amplitude of pupil plane was unknown .The results show that the new algorithm can reach higher accuracy of phase retrieval and lead to precise retrieval of optical field on any planes.关键词
