Abstract:
    The invention relates to the micro-displacement and hologram printing technology of the optical-mechanical-electrical integration. In which, it is used to effectively eliminate the impact of the printing results caused by the phase-changing of optical field and to control the pattern-changing. The mentioned system includes: a system which is used to separate the coherent laser beams of any perspective and to realize the optical fibers from non-coherent light-conditioning, and a measurement system which is used to measure the light intensity of the interfered light fringes, and a feedback control system which is used to change the light intensity information into the controlling signal to achieve phase lock.
