Computer-generated hologram manipulation and fast production with a focus on security application

Motivated by the successful printing of a computer-generated hologram using the computer-to- film (CtF) graphic process, we present a further refined technique with increased resolution, applicable in security. The CtF process offers low cost and fast production while persevering high resolution, and it can make every hologram unique. In this paper, we present the improvement of the printing method, with several software modifications and the implementation of security features at different levels of production.
