Abstract
Official abstract text for this publication.
Methods and systems for performing dynamic aperture holography are described. Examples include a method of recording multiple holograms in a photosensitive recording medium, where multiple signal beam angular apertures used to record the multiple holograms differ from each other. The multiple signal beam angular apertures can facilitate using a larger range of reference beam angular apertures. The multiple holograms are typically multiplexed, and examples of dynamic aperture holography enable packing the multiplexed holograms more densely in the recording medium. Some dynamic aperture holography systems include monocular objective lens architecture.
First claim
Opening claim text (preview).
We claim: 1. A method of using dynamic aperture holography for recording multiple holograms, the method comprising: generating a first signal beam by encoding data into a nascent signal beam using a data encoding element, wherein the data encoding element includes an inactive portion that does not have data encoded therein; projecting the first signal beam through an objective lens into a photosensitive recording medium at a first signal beam angular aperture; projecting a fir…
