A new fast-Fourier-transform-based model of a page-oriented holographic data-storage system is presented. The model accounts for essential system and storage material features (e.g. diffraction, noises, and saturation) and provides reliable results in the form of output images, histograms, or bit-error rates. The model is built on a modular basis and provides the possibility of working with different system versions, key components, and storage materials. Applications of the method are presented through examples of optimization of the data density, reference beam size at Gaussian beam illumination, and calculation of the storage medium's positioning tolerances in accordance with the results of test measurements.
提出了一种基于快速傅里叶变换的面向页面全息数据存储系统新模型。该模型考虑了系统和存储材料的基本特征（如衍射、噪声和饱和度），并以输出图像、直方图或误码率的形式提供可靠结果。该模型基于模块化构建，提供了使用不同系统版本、关键组件和存储材料的可能性。通过数据密度优化、高斯光束照明下参考光束尺寸以及根据测试测量结果计算存储介质定位公差等示例，展示了该方法的应用。
