发明名称 METHOD FOR HOLOGRAPHIC DATA RETRIEVAL BY QUADRATURE HOMODYNE DETECTION
摘要 Systems and methods are provided for recovering data in a holographic memory system. One embodiment of these systems and methods uses homodyne detection to introduce a local oscillator beam into a reconstructed data beam of the recovered hologram. An image of the combined beam comprising the reconstructed data beam and local oscillator beam may be processed to obtain contrast level information for the pixels of the detected image. This contrast level information may then be used to obtain an increased contrast image of the recovered hologram, which may increase the SNR of the recovered data.
