Device for holographic recording of data, has recording medium generating output object beam, where object beam serves as incident object beam on another recording medium after object beam is passed through forming optical system

摘要

The device has a deflecting unit (6a) for deflecting a parent reference beam into a deflected reference beam (7a). A recording medium (4a) of an upstream optical module (11) generates an output object beam (20a) from an incident object beam (2a). The output object beam serves as another incident object beam (2b) on another recording medium (4b) of a downstream optical module (12) after the output object beam is passed through a forming optical system of the downstream optical module.
