Abstract

Recently the technology of hologram receives a lot of interest owing to its advantages and many researches on hologram recordings have been actively studied. In some studies, digital hologram printing methods have lots of applications because of the ability to record large area hologram based on the technique of holographic stereogram. The holographic stereogram printing method records the hologram composed of hogels which are the unit of the hologram recorded at once. This method has advantages in flexibility of the size since it records the hologram hogel by hogel. In addition, the hologram printer records not only wavefront of real objects captured by charge coupled device (CCD) but also hologram patterns of virtual objects calculated by computer-generated hologram (CGH) algorithm. In previous systems, it is difficult to implement the hologram in high resolution because of the low numerical aperture of hogels. In this paper, we suggest the method of recording high-resolution hologram using binary wavefront pattern and discuss the optical modulation properties of the printed binary pattern.
