A new long-distance linear dis- placement measuring system is designed by utilizing one 1-bit mult-i turn optical encoder and the mechanism comprised the gearing w heels and the conveyor belt. The experimental results prove that the corrected systemic errors can be diminished in less than 0. 0 5 mm and the industrial measurement with medium and low accuracy requirements can be met entirely .
