Abstract
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.

Among them is holography, which has been thought as an ultimate method for describing 3D information since it is capable of reconstructing the whole wavefront of a recorded object wave
Since II provides a compact pickup process in which 3D information is captured under an incoherent light source, the high requirements of the traditional holography recording process can be alleviated
