Paper Abstract

An optical correlator as a part of the potential, hybrid system for exact positioning of phase objects in robotics (microrobotics) is proposed. Particularly, a coherent correlator system with image plane in which the required optical correlation is formed in output plane is used. Positive photographic transparency of the object, recorded by phase-contrast method serves as matched filter. The values of light intensity measured in central point of the output plane are related to the actual positions of the input object and allow for searching after required location of the object. The proposed correlator system has been tested experimentally. The obtained results are consistent with the theory.
