| OPTICAL DATA PROCESSING LABORATORY COURSES
The course includes the following laboratory works: • Optical bistability • Intensity self-oscillations and optical chao • Optical logic element • Spatial image filtering The laboratory works are performed with the use of a fundamental component base and the unique equipment involving liquid-crystal (LC) cells. The components are easily adjusted with magnetic holders at a metallic plate measuring no less than 600 800 mm.
 Optical bistability: • Optical bistability and its realization conditions • Characteristics of optoelectronic LC system with feedback • Control over the hysteresis loop of LC system • Analysis of the modes of differential amplification, discriminator, limiter Intensity self-oscillations and optical chaos: • Theoretical principles of nonlinear oscillations • Self-oscillations and stochastic operating modes of coupled optoelectronic LC elements • Analysis for Fourier-spectra of signals and phase traces • Procedures to attain optical chaos Optical logic elements: • Basics of digital data processing • Principles of constructing optical logic elements • Schemes for realization of optical logic operations based on optoelectronic LC cells • Characteristics of LC elements and realization of the main logic operations Spatial image filtering: • Principal concepts and relations of Fourier-optics • Study of the schemes for optical data processing using spatial image filtering • Spatial Fourier-spectra. Isolation of particular fragments (letters, symbols) and contrast control The equipment proposed enables research associated with the deve-lopment of new information processing techniques and design of multi-functional optoelectronic elements. |
