Detailed Description

Introduction

Light field based CGH generates the complex field from the light field.

Light field images are the projection images of 3D object from different view points.

The algorithm gives random phase distribution to each pixel in each projection image. Light-ray information of each pixel is conversed to the wavefront in ray-sampling(RS) plane using fourier transform of phase distributed amplitude.

Hologram complex field is obtained after wave propataion from RS planes to CGH plane.
