Abstract

We describe a multichannel correlator/convolver architecture utilizing an acoustooptic light modulator for the 1-D input channel and a magnetooptic spatial light modulator (MOSLM) for the second 2-D parallel channel. The MOSLM allows greater parallelism to be implemented into this correlator/convolver design than was previously reported. We demonstrate the implementation of 24 parallel channels with a 48 x 48 device. We present experimental data and discuss ways of increasing the number of parallel channels using commercially available MOSLMs and other previously discussed techniques such as frequency multiplexing. We show that over 2000 parallel channels are possible at 32-bit accuracy. A technique for obtaining a limited gray scale is also discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
