近年来，在体全息介质中研究了相位码复用数据存储作为角复用或波长复用的替代方案。相位码复用允许使用固定的几何形状和波长来实现，从而导致潜在的快速访问时间和在光学系统中级联的可能性。此外，有人建议使用部分相位码可以直接重建存储图像的某些和和差。我们演示了在参考波束路径中使用复合相位和幅度调制器来召回存储数据页的任意线性组合
Recently phase code multiplexed data storage in volume holographic media has been investigated as an alternative to angular or wavelength multiplexing. Phase code multiplexing allows implementation with fixed geometry and wavelength, resulting in potentially fast access times and the possibility of cascading in an optical system. In addition, it has been suggested that use of partial phase codes can be used to directly reconstruct certain sums and differences of stored images. We demonstrate the recall of arbitrary linear combinations of stored data pages by using a compound phase and amplitude modulator in the reference beam path.<<ETX>>
