Paper Abstract

Modified light-diffusion patterns created by contact-copy interference of diffused laser lights are proposed. A conventional light-diffusion pattern is created by means of a diffuser and a noncontact photosensitive plate (a noncontact or sandwich method). The proposed method uses a contact photosensitive plate and allows implementation of new applications such as surface-relief holograms, anticounterfeiting, and light-diffusion eyemarks.
