  • Laser interference displacement measuring system capable of automatic laser path alignment
    Patent number: 5739907
    Abstract: A laser interference system comprises a laser head, an interference lens, a reflector, an optic fiber transmission set, and an automatic laser path alignment unit having a photodiode, a data processing member and a control member. The photodiode is capable of sensing the position of the reflecting residual light of the reflector. The output signal of the position of the reflecting residual light is processed by the data processing member to become the electric voltage, which is transmitted to the control member for regulating the relative lateral displacement between the interference lens and the reflector.
