title = "Test method for FOG loop eigenfrequency and half-wavevoltage based on square wave modulation",
abstract = "A novel approach was presented to solve the problem of fiber optic gyro(FOG) loop eigenfrequency and half-wavevoltage measuring. The method comes from the mechanism of reciprocal shift modulation, insteads of measuring loop eigenfrequency it measures the optics power of ineffective-modulation that having a peak; and insteads of measuring half-wavevoltage it measures the optics power of effective-modulation that having a low plain part. The modulation square wave whose frequence and amplitude could be programmed is made of the technique of direct digital synthesis. The scheme was tested by Matlab simulation, and implemented in circuit. The result of the loop eigenfrequency and half-wavevoltage is much more preciser than handwork test, what's more, it takes much less time.",
