Abstract

A page-oriented, angle-multiplexed volume holographic optical-memory recording system has been constructed. This memory is addressed by the use of an acousto-optic deflector with a random-access time of 16 µs per page. This enables data transfer rates of 5.28 Gbits/s when pages of binary data are being stored. The reconstruction quality of images stored as memory pages is assessed with the quality achieved with the acousto-optic device compared with that achieved with the original recording optics.

摘要

已构建了一种面向页面、角度复用的体全息光学存储记录系统。该存储器通过使用声光偏转器进行寻址，每页的随机存取时间为16微秒。当存储二进制数据页面时，这使得数据传输速率达到5.28 Gbit/s。将存储为存储器页面的图像的重建质量与使用原始记录光学器件所达到的质量进行比较，以此来评估声光器件所实现的质量。
