  • Patent number: 10473889
    Abstract: An experimental system for laser beam measurement and steering control, and relates to the technical field of optical, mechanical and electronic integration experimental systems. It includes: a high-precision optical mirror, a piezoelectric micro-actuator, a vibration exciter, a signal collection subsystem, a laser emitter, a beam splitter mirror, a fast steering mirror, a mechanical vibration isolation air bearing table, an optical vibration isolation air bearing table, a data processing and analyzing subsystem, and data transmission lines and power supply lines between subsystems and components. It uses a deflection angle of the laser beam as a control variation, can not only precisely measure the deflection angle of the laser beam, but also inhibit vibration of the high-precision optical mirror by using the piezoelectric micro-actuator and directly adjust the steering of the emitted laser beam by using the fast steering mirror, thereby improving precision of beam steering control.
