This is because of the small recording area of the electronic record device (CCD), so the recorded digital hologramresolution is very low and the reconstruction image quality is affected greatly.
这是由于电子记录器件CCD的记录面积小，所记录数字全息图的分辨率低，这大大影响了再现像的质量。

It is verified experimentally that higher diffraction efficiency and resolution can be obtained by optical fiber image plane hologram.
认为光纤象面全息图可以获得较高衍射效率和分辨率，并对此进行了实验验证。

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.
