Title: Method for detecting signal and method for detecting fluctuation of phase modulation degree
Inventor: NISHIURA YOZO
IPC: G01C19/72
Filed: 1994-01-10
Abstract: PURPOSE:To detect the rotation angular velocity of a fiber coil by providing a phase modulator, and modulating the phase of the transmitted light periodically, and converting a change of intensity of the right-handed and left-handed interference light into the alternating current signal to fetch it, and obtaining a difference of duration between the right-handed and left- handed light included in one cycle of the modulation. CONSTITUTION:Two beams are transmitted as the right-handed light and the left-handed light in a fiber coil 6, and a phase modulator 7 modulates the phase periodically. A light receiving element 8 makes both the light interfere with each other and detects the intensity of the interference light. A capacitor 10 fetches the only alternating current, and the out put of the alternating current signal is reversed by a zero-cross detector 11 when the reverse rotation of the signal code is generated certain times. The zero-cross detector 11 detects a moment that the input signal passes through zero volt, and a counter 12 counts the number of passing through zero volt. With the rotation of the coil 6, a difference of the time for receiving the phase modulation is generated between both the right-handed and the left-handed light to make the output of the light receiving element 8 asymmetry. Consequently, a difference is generated between durations T1 and T2 of a first and a second period of the zero-cross counter. Angular velocity is obtained on the basis of a difference of the durations DELTAT=T1-T2.
