Information Transformation Algorithms in Echo-Holography

The filtering of optical signals and the transformation of information using stimulated echo-holography is examined in the case where it is excited by an information-carrying object laser pulse and a pulse that serves as a frequency filter. It is shown that the shape of the response of the stimulate...

Description
Summary:The filtering of optical signals and the transformation of information using stimulated echo-holography is examined in the case where it is excited by an information-carrying object laser pulse and a pulse that serves as a frequency filter. It is shown that the shape of the response of the stimulated echo hologram depends on the duration, amplitude, area, and temporal structure of the exciting pulses. This can be used for logical operations with signals.
