Abstract

This system provides rapid location of free form text retrieved from an optical disk by content addressing. A highly parallel, spatial intensity integrating correlator has been breadboarded using commercially available off-the-shelf components for proof of concept and identification of key component characteristics. Performance is found to be sensitive to light source coherence, optics modulation transfer function, media bit placement and contrast uniformity. Simplified processing algorithms extendable to on-chip implementation are evaluated with simulated and experimental results.
