ABSTRACT = {Tabletop integral imaging display with a more realistic and immersive experience has always been a hot spot in
three-dimensional imaging technology, widely used in biomedical imaging and visualization to enhance medical
diagnosis. However, the traditional structural characteristics of integral imaging display inevitably introduce the
flipping effect outside the effective viewing angle. Here, a full-parallax tabletop integral imaging display without
the flipping effect based on space-multiplexed voxel screen and compound lens array is demonstrated, and two
holographic functional screens with different parameters are optically designed and fabricated. To eliminate the
flipping effect in the reconstruction process, the space-multiplexed voxel screen consisting of a projector array and
the holographic functional screen is presented to constrain light beams passing through the corresponding lens. To
greatly promote imaging quality within the viewing area, the aspherical structure of the compound lens is optimized
to balance the aberrations. It cooperates with the holographic functional screen to modulate the light field spatial
distribution. Compared with the simulation results, the distortion rate of the imaging display is reduced to less
than 9% from more than 30%. In the experiment, the floating high-quality reconstructed three-dimensional image
without the flipping effect can be observed with the correct 3D perception at 96° × 96° viewing angle, where 44,100
viewpoints are employed.},
