Abstract: An optical linear encoder for converting scanning light beams incident thereupon into a series of pulsatory light comprising light transmission parts for passing through the scanning light beams and light non-transmission parts for blocking transmission of the scanning light beams. The light non-transmission parts are alternately arranged with said light transmission parts in predetermined intervals that are determined by the amount of distortion inherently occurring in an optical system through which the scanning light beams travel.
