Abstract
We calculate the Fourier transform of two-dimensional data from the camera input of a real three-dimensional image and create a hologram. Depending on the phase modulation, a hologram can be either a kinoform or a phase hologram. Kinoform has been studied previously. They produce a reactivation image, but matching is difficult because noise arises when using only phase information. Therefore, we propose a method to produce a phase hologram with a high precision system that creates a hologram based on interference fringes using the phasing and amplitude of the new system and displays the intensity distribution on a phasing device. The liquid crystal device tested with this system shows a degree of phase modulation of greater than 2π and a high diffraction efficiency. We compare the kinoform with a phase hologram using a high resolution liquid crystal device that modulates the phase and report that the phase hologram demonstrates better performance.
