Optical homodyne processor
TLDR
An analog optical processor which performs complex transform operations oromplex correlations to yield quantitative (numerical) output is accomplished on data points which are used as inputs serially or simultaneously as mentioned in this paper.Abstract:
An analog optical processor which performs complex transform operations oromplex correlations to yield quantitative (numerical) output. This is accomplished on data points which are used as inputs serially or simultaneously. The dynamic range of the input function that may be operated upon is not limited, as heretofore, by the characteristics of a medium on which the input function is recorded or stored. The dynamic range of the output is also not limited by the characteristics of a discrete electro-optical sensor.read more

Personal and property identification system
TL;DR: A system for identification of a person (P, P') or an object with an informon carrier (1, G, 20), including at least one identification (IA, IB, IC; K) not perceptible with a human sense organ characteristic for a certain person or object (G), was described in this paper.

Real-time programmable optical correlator
TL;DR: In this paper, a real-time programmable joint transform optical correlator incorporating a magneto-optic spatial light modulator and a liquid crystal light valve was proposed, where cross correlation between the input functions (signals) are obtained through the inverse Fourier transform of the read out coherent illumination and are subsequently output from the correlator.

Acousto-optic system for testing high speed circuits
TL;DR: In this paper, an optical system for testing the operation of very high speed logic devices is described. But the authors focus on the use of a laser light source to send a short light signal through the spatial light modulator and onto a light detector array, which corresponds to the bit stream of data from the output of the device under test.
