Abstract

PURPOSE:To eliminate mutual interference between a driving side and a detection side and to detect Coriolis force by detecting the displacement of the vibrator of the vibration gyroscope optically by a driving piezoelectric element. CONSTITUTION:One end of an optical fiber 12 is connected to a light emitting element 11 provided on the side of the casing 2 of the gyroscope 10 and penetrates the center of the arm part 3b of the tuning fork type vibrator 3 in parallel to its vertical center axis (b) and reaches the tip part of the arm part 3b. Then light which is emitted by the element 11 and passed through the fiber 12 is detected by a two-dimensional photodetector 13 fixed to the casing while photoelectric transducers are arranged, thereby finding the displacement of the vibrator 3. At this time, the vibrator 3 is driven by the driving piezoelectric element 5 fitted outside the arm part 3b to perform detection optically, so there is no interference caused between the driving side and detection side and an error due to the influence of the driving side is small.
