摘要:
A gyro comprises a ring resonator type laser, a vibration table for applying an oscillation to the laser, and a signal processor for processing an output signal from the laser. The signal processor determines the phase angle of the output signal from the amplitude of an oscillation cycle component of the vibration table and that of a higher harmonic component thereof.
