Two-dimensional optical processing using one-dimensional input devices

TL;DR: A defect inspection method and device for irradiating a linear region on a surface patterned sample mounted on a table, with illumination light from an inclined direction to the sample, next detecting in each of a plurality of directions an image of the light scattered from the sample irradiated with the illumination light, then processing signals obtained by the detection of the images of the scattered light, and thereby detecting a defect present on the sample as discussed by the authors.

TL;DR: In this paper, an integrated acousto-optic Bragg modulator with a planar waveguide, a linear TIPE micro-lens array, a 500MHz surface acoustic wave transducer, and an integrating lens have all been integrated in a substrate size of 0.2×1.0×2.0 cm to form an integrated ACO-BRG modulator that should find a variety of applications in optical computing, signal processing and communications.

TL;DR: A novel identity is established for the matching polynomials of complete bichromatic graphs which implement the intrinsic connections between neurons of local networks located in neural layers.

TL;DR: An optical multifunctional processor that can perform logic, numeric, pattern recognition, morphological, and inference operations, based on an optical correlator architecture, which is a multiple-instruction multiple-data processor.

TL;DR: In this paper, near real-time reusable spatial light modulators for coherent optical data processing are reviewed and the PROM, liquid crystal, and electron beam modulators are compared.

TL;DR: In this article, a coupled mode formulation is developed for the analysis of acoustooptic diffraction with multiple acoustic waves at different carrier frequencies for the Raman-Nath regime, analytic solutions are obtained for N s i g n a l s In the Bragg (thick ultrasonic grating) limit, analytic solution is obtained for two independent signals.

TL;DR: It is shown how certain algorithms for matrix-vector multiplication can be implemented using acoustooptic cells for multiplication and input data transfer and using CCD detector arrays for accumulation and output of the results.

TL;DR: In this paper, various microwave processes, including synthetic-aperture radar and linearly frequency-modulated pulse compression, are described as analogs of holography, and the holographic viewpoint often leads to a new understanding and to new methods of signal processing.
