摘要：
During the numerical reconstruction process of synthetic aperture hologram by use of screen-division method, the center change of the digital reconstruction plane will influence the positions and the phase distributions of the corresponding reconstructed images from the sub-holograms, which will affect the quality of the synthetic numerical reconstruction image. For synthetic aperture digital lensless Fourier transform hologram, a screen-division reconstruction method is proposed based on theoretical analysis. It is pointed out that, in order to get the accurate synthetic numerical reconstruction image, the sub-reconstructed images should multiply with the phase correction factor according to the position of the corresponding sub-holograms on the synthetic aperture hologram plane and then be superposed. Taking the digital lensless Fourier transform hologram with large area acquired by use of linear CCD push-broom technology as example, the screen-division numerical reconstruction experiment is conducted according to the proposed method, and accurate synthetic numerical reconstruction image with high quality is acquired. The experimental result is consistent with the theoretical analysis.
