INTERFEROMETRIC DEVICE FOR MEASURING AN ANGULAR ROTATION VELOCITY |
摘要 |
An interferometric device for measuring an angular rotational speed comprising an amplifying photo refractive crystal placed in the path of optical guide means forming a closed loop. Two signal waves penetrate into said crystal so as to obtain two contrarotating waves of different optical frequencies and of amplitudes restored by amplification in the crystal, moving in said closed loop. |
