IPC: G01C19/72
Filed: 1993-11-08
Abstract: PURPOSE:To prevent the variation of scale factor due to variation in the wave- length of light source by shifting the phase of carrier signal (reference signal) in some direction with respect to the basic wave component of output from a light receiving element. CONSTITUTION:The phase of a carrier signal is shifted by an angle theta from the basic wave component and the angle theta is set such that the product Kcostheta of costheta and a scale factor K(the ratio between the detection signal from a light receiving element 9 and the rotational angular speed of a fiber coil 5) will be constant regardless of the temperature. The angle theta and the factor K are functions of temperature. When the frequency fS of a crystal oscillator 14 is set equal to 2<n> of the phase modulation frequency, the phase modulation frequency is clocked at 2<n> by a clock fS. Consequently, one phase difference is clocked at 2pi/2<n>. The step of shift angle theta is set equal thereto and the phase of sensor signal (output signal from the element 9) or carrier signal is varied step by step. A phase for which the variation of factor K is minimized is then determined and the shift angle theta is fixed thereat.
