Abstract: Method for readout from multiscale encoders wherein the fine readout digits information signals formed in Gray code by means of light flux modulation from the fine readout code mask graduations are transformed into electrical signs by photosensitive read elements. Interaction of the sensing element with the most significant digit code intervals of the full range fine readout masks forms an imitating electrical signal, the logical level transition of which occurs every time that the coarse readout digits information signals logical level must be changed.
