We introduce a phase-only hologram generation method based on an integral
imaging, and propose an enhancement method in representable depth interval. The
computational integral imaging reconstruction method is modified based on optical
°ow to obtain depth-slice images for the focused objects only. A phase-only hologram
for multiple plane images is generated using the iterative Fresnel transform
algorithm. In addition, a division method in hologram plane is proposed for
enhancement in the representable minimum depth interval.
