Abstract:
    A device used to measure angular speed pointing to scanning mirror is prepared as using optical unit to convert angular micro variation pointing to scanning mirror to be intensity signal interfered by laser beam, utilizing detector to convert light intensity signal to be electric signal, using inversion software stored in internal memory of PC computer to obtain angular speed pointing to scanning mirror after electric signal is processed by information processing module.
