Because of its simple optical system setup and robust noise tolerance, non-interferometric phase retrieval is an important technique for phase-modulated holographic data storage. Usually, the iterative algorithm of non-interferometry needs hundreds of iteration numbers to retrieve phase accurately, the data transfer rate decreases severely. Strong constraints such as adding embedded data into the phase data page can reduce the iteration numbers, but this method decreases the code rate severely. In this paper, we proposed the advanced non-interferometric phase retrieval method based on the collinear system. By encoding the reference beam of the collinear optical holographic storage system with embedded data, the storage space of the signal beam data page is completely released and the encoding rate is doubled. The embedded data can provide more modulation index including phase and amplitude to shorten iterations, so the data transfer rate is also increased. In the simulation, we recorded a four-level phase pattern and retrieved the phase correctly.

由于其简单的光学系统设置和强大的噪声承受能力，因此非干涉式相位检索是用于相位调制全息数据存储的一项重要技术。通常，非干涉法的迭代算法需要数百次迭代才能准确地获取相位，数据传输速率会大大降低。诸如将嵌入式数据添加到阶段数据页面中的强大约束可以减少迭代次数，但是此方法会严重降低编码率。在本文中，我们提出了一种基于共线系统的高级非干涉相位检索方法。通过用嵌入的数据对共线光学全息存储系统的参考光束进行编码，信号光束数据页的存储空间被完全释放，编码率提高了一倍。嵌入的数据可以提供更多的调制索引，包括相位和幅度，以缩短迭代，因此数据传输速率也得到提高。在仿真中，我们记录了四级相位模式并正确检索了相位。
