提出了两种方法来提高自参考全息数据存储（SR-HDS）中信号的读出质量，其中不需要参考光束来全息记录和读取数字数据：离焦（OtF）方法和过采样附加图案（OsAP）方法。在OtF方法中，焦点位于记录介质的外部，并且用具有比OsAP方法中的信号图案更高的空间频率的附加图案来记录信号图案。实验结果表明，两种方法都能有效地大幅提高信噪比（SNR）。此外，通过数值模拟可以观察到，通过实现均匀全息图分布，读出质量得到了提高。
Two methods are proposed to improve the readout quality of signals in self-referential holographic data storage (SR-HDS), in which no reference beam is required to record and read digital data holographically: the off-the-focus (OtF) method and the oversampling additional pattern (OsAP) method. The focal point is located outside of the recording medium in the OtF method, and the signal pattern is recorded with an additional pattern that possesses a higher spatial frequency than the signal pattern in the OsAP method. Experimental results show that both methods are effective for drastically improving the signal-to-noise ratio (SNR). In addition, through numerical simulation, it can be observed that the readout quality is improved by the achievement of homogeneous hologram distribution.
