FIBER OPTIC GYROSCOPE MODULATION ERROR REDUCTION (FIBER OPTIC GYROSCOPE MODULATION ERROR REDUCTION)

摘要

Fiber optic gyroscope modulation error reduction device;The error control device for the optical fiber rotation sensor (FIG. 1) has an electromagnetic wave that propagates in the opposite direction through the bias optical phase modulator 19, which biases the optical phase modulator 19 Two-wave distortion can be controlled.;Control of the bias optical phase modulator 19 for the modulator having the piezoelectric body 30 wrapped with the optical fiber portion 40 is achieved by fixing the body between the layers 33 and 35 of non-linear cured material.
