Paper Abstract

Computer generated holograms (CGHs) require high resolution output devices. However, resolutions of current LCDs are not high enough for practical use. This causes a narrow visual field and viewing zone, conjugate images, ghost images, and 0th-order light which hinder our view. We propose a method for solving these problems. Moreover, the enlargements of the visual field were realized by changing the distance of reconstruction light source. However, the shapes of 3-D objects were distorted using this method. We have solved the problem by correcting CGH data and confirmed the effectiveness of our method in the optical experiments.
