Enlargement of Object Reconstruction Area in Computer-Generated Hologram using the Fourier Transform Optical System

Abstract

Computer-generated hologram (CGH) is a hologram generated by simulating recording process in optical holography. High resolution output devices are required to observe 3D images. However, resolution of output devices is not high enough to display interference pattern. Therefore, viewing zone and visual eld are limited. To improve these problems, this paper proposes a method for enlargement visual eld by enlarging reconstruction area in CGH using the Fourier transform optical system. Optical reconstruction experiments were carried out, and results of these experiments showed that the proposed method enlarge visual eld and reconstruction area.
