PHASE MODULATION FIBER OPTIC GYROSCOPE |
摘要 |
A phase modulation type fiber optic gyroscope having a greatly improved output stability without a large increase in the number of basic components of the gyroscope system. In accordance with the invention, the d.c. component of the output of a light detecting element which provides the two circulating beams is sensed and employed to control the output of the light-emitting element so as to be constant. |
