由于全息图的信息量是如此巨大，数据压缩对于实用的电子全息显示系统是重要的。因此，我们研究了块二次采样方法和插值的二次采样数据。然而，该过程也导致所显示的3D图像上的模糊。因此，在信息减少率和图像模糊之间存在折衷关系。将2D图像压缩应用于全息图是不实际的，因为全息数据的特性与2D图像的特性完全不同。我们已经证明了二维压缩技术可以有效地用于压缩条纹图，首先分割它，然后执行一个变换操作后，我们讨论了理论和实验结果，并比较了这两种压缩方法的图像质量。
Since the information content of a hologram is so huge, data compression is important for a practical electroholographic display system. We have therefore investigated the block subsampling method and the interpolation of subsampled data. This procedure, however, also causes a blur on the displayed 3D image. Therefore, there is a trade-off relation between the information reduction rate and the image blur. It is not practical to apply 2D image compression to a hologram because the character of the holographic data is quite different from that of a 2D image. We have demonstrated that 2D compression techniques can be used effectively to compress the fringe pattern by first segmenting it and then performing a transform operation upon it. We have discussed both theoretical and experimental results and have compared the image quality of those two compression methods.
