| 摘要 |
<p>The present invention relates to a reference beam coupler (50) for an apparatus for reading from and/or writing to holographic storage media (36), to a multiplexing scheme using the reference beam coupler (50), and to an apparatus for reading from and/or writing to holographic storage media (36) using such reference beam coupler (50) or multiplexing scheme. According to the invention, the reference beam coupler (50) has:
- a substrate (51);
- one or more optical fibers (25) passing through the substrate (51) for coupling one or more reference beams (41); and
- a reflective area (53) on the substrate (51) for reflecting an object beam (26).</p> |
