  • In order to study the problem of aperture synthesizing in digital holography,the method of theoretical analysis and experimental verification was adopted.The fundamental principle of recording and numerical reconstruction of the synthetic aperture digital holography was introduced.It was proved that the most important factor was synthesizing all the sub-holograms precisely to get the high resolution.A new method based on gray correlation algorithm for solving the problem on how to synthesize sub-holograms precisely was proposed.The principle of the algorithm was introduced and the precision was analyzed.The experiment results show the feasibility of the algorithm.
