“…Since relationship matrices are processed via a matrix-vector product, a learning process can be realized simply using rules operation (matrix-matrix multiplication) and implemented optically using the above proposed optical correlator as shown in Fig. 4 [22], [23]. In this figure, an input light beams representing a set of symbols is applied to the system using a 1-D SLM.…”

“…In this section we adopted the work published by Guilfoyle [23] in which optical comparisons can be performed based on the exclusive-or (EX-OR) primitive using dual-rail logic. Since both the value of the bit and its complement are needed for the comparison, each n-bit word will be represented by 2n light beams (i.e.…”

In this paper we propose a digital opto-electronic 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 on-the-fly by the optical computer. Only data that satisfy a particular query are converted into electronic signals and transferred to the end-user. A combination of two-dimensional 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.
