| Popis: | In order to improve the quality of digital hologram of large size object,a method of recording large size object with a short distance is presented.With spherical wave as reference wave,the digital hologram of large size color object image,which is illuminated with differently wavelengths(red,green,blue),is recorded by using of optic system with negative lens.Then each monochromatic holographic image is reconstructed with the same magnification,and the corresponding digital color holographic image is acquired by accurately synthesizing the reconstructed monochromatic images.In order to improve quality of reconstruction image,two elimination zero-order methods are proposed.At first,the zero-order is eliminated with two recorded hologram,and SLM is used to change the record parameters.And the zero-order and conjugate images are eliminated by using "no disturb hologram" in another method.The result will provide a reference in holography application and digital holographic test of large size object. |
