SGER: Thermal Fixing Method for Volume Storage

9618891 Fiddy光折射存储现在是一个大的国家努力的焦点，通过PRISM（光折射信息存储材料联盟）。 在使用卷存储介质时，他们面临的主要问题之一是选择性修复和擦除。 PI认为，使用更容易获得的锂酸锂材料，可以采用直接方法达到这些要求。 他们提出，人们可以通过光学方式寻址掺杂的锂酸盐，这样就可以局部加热晶体内部的小体积，同时写入要存储的信息。 这样的方法假设信息的本地存储是全息的，从而最小化在一个卷中写入的一组“页”之间的串扰，因为它们是通过相邻卷写入和读取的。 激光感应加热效应允许非机械光束转向，这是卷存储介质的另一个期望属性。 为了证明这一想法的原理，我们将首先使用一个便宜且不特别紧凑的二氧化碳激光器来进行局部加热。 ***

9618891 Fiddy Optical storage in photorefractives is now the focus of a large national effort, through PRISM (Photorefractive Information Storage Materials consortium). One of the major problems in using volume storage media that they face is that of selective fixing and erasing. The PI's are of the opinion that a straightforward method to achieve these requirements is possible using the much more readily available material of lithium niobate. They propose to show that one can optically address doped lithium niobate in such a way that one can locally heat a small volume interior to the crystal, while writing simultaneously the information to be stored. Such an approach assumes local storage of information holographically, thereby minimizing the cross-talk between the set of "pages" written in one volume as they are written and read through adjacent volumes. A laser induced heating effect allows for non-mechanical beam steering, which is another desirable attribute of volume storage media. In order to demonstrate the principle of this idea, we would first use an inexpensive and not particularly compact carbon dioxide laser to perform the localized heating. ***
