Abstract:
Conventional computer-generated holograms (CGHs) consist of regularly spaced square pixels, which, when replayed, exhibit many repeated higher orders. Furthermore, such pixellated CGHs are not well suited to printing using a conventional laser printer. In this Letter a novel method is presented that exploits the characteristics of a conventional laser-printing process to generate holograms with replay fields that exhibit markedly suppressed higher orders.
