Abstract
The image hologram can be reconstructed by the white light because the recorded image is placed very close or overlapping on the hologram to reduce the chromatic image blur. Since the file size of the practical hologram becomes huge, the hologram is divided into small segments. In our previous study, each segment is calculated independently and it causes the problem of the intensity fluctuation between segments, which makes the image observation very annoying. This fluctuation is also the problem for the computer-generated rainbow hologram. In this paper, we propose a method to eliminate the intensity fluctuation by the global normalization of the hologram. The experimental results are also shown.
