METHOD FOR DETERMINATION OF DISPLACEMENT OF AXIS OF CODE DISC OF ABSOLUTE OPTOELECTRONIC INDICATOR OF ANGLE

摘要

Method for determination of displacement of axis of code disc of absolute optoelectronic indicator of angle at which as additional detector one uses second single-line photo-matrix, and displacement of axis of code disc along the axis of photo-matrix is determined by angles between the reference of disc and boundaries of sectors that are projected to references of photo-matrixes and by displacements of boundaries of shadows of sectors with respect to references of photo-matrixes by formula :,where:- displacement of center of code sequence along axis of photo-matrix,- angle between reference of disc and boundaries of sectors that are projected on centers of photo-matrices,...- distance from center of photo-matrix to boundaries of shadows of sectors that are projected to center of photo-matrix.
