Abstrakt: A summary of the main known forms of moiré fringes for visual metrological applications is given. To observe and track displacements of a moving fringe in a conventional moiré system presents certain difficulties, as the individual fringes have no distinctive character. New types of moiré fringes were found and are discussed, where a recognizable unique fringe indicates an also unique position of a grating, displaced relative to its stationary counterpart.
