摘要： A collinear holographic storage system of a reflection type without needing additional configuration component by using standard beam is provided to increase data capacity by completely overlapping data capacity by reflecting target beam toward holographic storage media. A collinear holographic storage system(1) of a reflection type includes a spatial light modulator(14). The spatial light modulator inserts data page on an object beam(15). The spatial light modulator is located within a beam path of a beam part through a holographic storage media(9). By inserting data page on the transmitted reference beam the object beam is generated. The diameter of the reference beam of the holographic storage intra medium coincides with the diameter of the object beam. The focus of the reference beam is moved about the focus of the object beam. The diameter of the reference beam of the holographic storage intra medium is in accord with the diameter of the object beam. A second lens(11) is provided by the first optic.
摘要翻译：通过使用标准光束不需要附加配置组件的反射型共线全息存储系统被提供，以通过将目标光束反射到全息存储介质上完全重叠数据容量来增加数据容量。反射型共线全息存储系统（1）包括空间光调制器（14）。空间光调制器将数据页插入物体光束（15）上。空间光调制器位于通过全息存储介质（9）的光束部分的光束路径内。通过在发送的参考光束上插入数据页，生成对象光束。全息存储介质中的参考光束的直径与物体光束的直径一致。参考光束的焦点围绕物体光束的焦点移动。全息存储介质的参考光束的直径与物体光束的直径一致。第二透镜（11）由第一光学元件提供。
