  • Optical multi-axis linear displacement measurement system and a method thereof
    Patent number: 7804605
    Abstract: The present invention provides an optical multi-axis linear displacement measurement system and a method thereof, and the system can detect the reflected light from the top surface of the object so as to obtain multi-axis linear displacements of the object. The optical multi-axis linear displacement measurement system utilizes a non-contact optical method for obtaining multi-axis linear displacements of the object and it can perform simultaneous multi-axis linear displacement measurements. The advantages of the system and method include: high response speed (bandwidth) for dynamic measurement, simple structure, cost effective, and high sensitivity for displacement measurements.
