    The pseudoscopic-orthoscopic conversion (POC) algorithm, which is applicable to asymmetrical capture and display of three-dimensional (3D) scene information, is utilized to perform the holographic stereogram printing. The matching relationship between pixels on the sampled image and the synthetic parallax image is obtained under different distances between the sampling plane and the holographic plane and different ratios of sampling interval to holographic unit size. The influences of exposure optical system parameters and POC algorithm parameters on the field of view of the stereogram are also analyzed, and the relationship between scene depth and field of view is obtained. The experimental results demonstrate the applicability of POC algorithm to holographic stereogram printing and the validity of the relationship between scene depth and field of view by reconstructing 3D objects at different scene depths. The resolution is reduced because of the reconstructed image ghosting when the depth of the scene is small, and reasons for the ghosting of the holographic stereogram are also explained. The accurate parallax image at the pixel level avoids the influence of data error on the quality of holographic stereogram, and has positive significance in improving the resolution of the reconstructed image.
