Paper Abstract

In this paper we propose a digital optoelectronic computer capable ofperforming a rich variety of full text search operations. Most of these operations require searching a significant number of documents to retrieve only a few pages. In the proposed configuration textual data are stored on optical disks retrieved in parallel and processed onthefly by the optical computer. Only data that satisfy a particular query are converted into electronic signals and transferred to the enduser. A combination of twodimensional spatial light modulators and photodetectors are used for array processing. In this way the system takes full advantage of the speed and parallelism of digital optical technology. Finally the implementation of a set of text processing operations is shown. 1.
