Abstract
Systems, methods, and devices are provided relating to far field hologram viewing devices. A method of designing and manufacturing a far field hologram is provided. Holographic light patterns with minimal spurious pixel errors in the hologram response may be produced without requiring a tight tolerance on the relative positions of the hologram and an observer's eye. Far field viewing devices, and methods for making the same, that employ multiple unit holograms each having differing noise characteristics that superpose in a way to reduce the effects of spurious pixel errors while maintaining good overall noise performance.
