Paper Abstract

Multimedia databases are characterized by massive storage requirements and the need for an extremely high processor/memory bandwidth. In addition, the diversity of data types and their varying sizes and formats make multimedia database processing a formidable task. Optical and optoelectronic technology can contribute devices and system solutions with high time-space bandwidth. Spatial light modulators constitute one such class of devices. In this paper, we outline the desirable properties of spatial light modulators for multimedia database processing and review a number of devices and the systems they have been used in. Special attention is paid to holographic associative processing. We also describe a free-space optoelectronic system that employs arrays of vertical cavity surface emitting lasers integrated on CMOS to perform similarity searches on databases of biological data.
