Abstract

This paper presents a planewave approximation based method to calculate the HPO hologram patterns of a 3D object. The proposed method, unlike the holographic stereogram, takes Fourier transform of horizontally sliced 2D images without the projection process, which makes it possible to reconstruct a higher resolution image with depth information. Starting from the ray-tracing based conventional digital hologram, we makes the derivation of the proposed method where the need for the segmentation of a hologram is described. From the computational point of view, we show the proposed method is quite advantageous over the conventional hologram, especially for wide horizontal viewing visualization. Finally, simulation results obtained by both methods are compared.
