Optical systems for efficient triple-matrix-product processing
Abstract
Three different optical systems are developed for efficient evaluation of a triple-matrix product of the form /U/ /G/ /V/. One system uses a purely space-integrating architecture, whereas the other two use hybrid time- and space-integrating architectures. Each of these three systems has a distinct format for input (using one-dimensional and two-dimensional spatial light modulators) and output (using wither 1-D or 2-D time-integrating detector arrays or high-bandwidth single-element detectors) devices, thus permitting a trade-off between parameters such as speed and dynamic range. Potential applications for these systems include image data compression and orthogonal transforms of coefficient matrices encountered in linear systems analysis.
