为了充分利用光学扫描全息系统的分辨率,提出了用环形光栅扫描物体的光学扫描全息术。其优点是:可以用非相干光源记录扫描全息图,系统为单光路,从而可以提高系统的稳定性。阐明了环形光栅光学扫描全息术的基本原理,并给出了实验结果

In order to fully use the resolution of optical scanning hologram system, a method of using circular grating to scan the objects is proposed for producing the optical scanning holograms.The advantages are that the incoherent light can be used to produce holograms and the stability of the optical system is increased as a single path system. The principle of the circular grating optical scanning holography and the experimental results are presented.
