Disjunction Operation for Signals in Optical Echo Holography

Abstract

© 2020, Springer Science+Business Media, LLC, part of Springer Nature. We consider the implementation of the logical operation of disjunction of signals using accumulated stimulated echo holography. We study the processing of information embedded in the laser pulses of a pulse pair, with one of the pulses in the pair being an object and the other one having a wide frequency spectrum. We show that, taking the pulse spectra as narrow frequency regions within the inhomogeneously broadened resonance transition line, it is possible to implement the disjunction operation in the frequency domain.
