全息数据存储被认为是最有前途的大容量数据存储技术之一。许多公司已经提出了几个全息概念并进行了详细的研究。这两个概念的不同之处在于在全息介质内叠加物光束和参考光束的方法。目前，最相关的概念是平面波概念、共线概念和反向传播光束的概念。我们比较所有三个概念，就其光束重叠，材料消耗效率，衍射效率和串扰特性。调查是通过数值模拟，它提供了定义良好的条件下，在所有的设置和独立的实验不确定性，如介质灵敏度的非线性行为和光散射或反射的影响。
Holographic data storage is considered to be one of the most promising technologies for high-capacity data storage. Several holographic concepts have been suggested and investigated in detail by many companies. The concepts differ in the method of superposing object and reference beams inside the holographic medium. At present, the most relevant concepts are the plane wave concept, the collinear concept, and a concept with counterpropagating beams. We compare all three concepts, with regard to their beam overlap, efficiency of material consumption, diffraction efficiency, and crosstalk characteristics. The investigation is performed by numerical simulations, which offer well-defined conditions in all setups and are independent of experimental uncertainties such as the nonlinear behavior of medium sensitivity and the effects of light scattering or reflection.
