Abstract: A displacement measuring system is disclosed. The system may implement a code carrier formed from a data storage medium which includes a relative displacement measurement code channel which is an arrangement of pit lines and bump lines. A composite subsystem may include an optical laser assembly, a signal processing unit, and a power driver, and can scan and decode the code carrier by focusing a laser beam on the code carrier and obtaining a group of radio frequency electric signals from the reflection of the laser beam which represents the bumps and pits of the code carrier. A central control and signal output unit can process the electric signals produced by multiple composite subsystems and output information representing incremental and absolute displacement.
