The result of testing and statistic analyzing for FOG signal indicates that the Allan variance means is successful in separating the main random error source of signal noise and the advantages of the wavelet threshold-value filter is verified.
The principle and classification of Fiber optic gyroscope(FOG) are introduced,the character of interferometric FOG(I-FOG),resonance loop cavity FOG(R-FOG) and stimulated brillouin scattering FOG(B-FOG) are reviewed,the structure feature,the good qualities and disadvantage,and future development of them are summarized.

Resonator fiber optic gyro(R-FOG)is a novel optical rotation sensor whose resonant frequency is changed due to the Sagnac effect. Loop frequency locking technique in phase modulation spectroscope technique R-FOG system has been researched.
A procedure for the visualization of these effects was proposed, and changes in the concentration of silver centers, which play the role of fog centers, were detected.
A procedure is suggested, which enables one to form in the central part of a combustion chamber a cloud of mixture containing hydrogen, air, steam, and water aerosol (fog) both at room temperature and at temperatures of up to 373 K.
