Abstract
New techniques for computer-generated hologram (CGH), for example full-color reconstruction, have been developed for the last few years. As a result, CGH are expected as a new digital art much more than before. However, programming skills were required to design and calculate CGHs. To ease this situation, software tools have been developed for non-expert people to calculate full-color CGHs. In this study, a series of application programs for large-scale CGHs, especially for full-color CGHs, are developed to calculate object fields, generate fringes pattern, and simulate its reconstruction without programming.
