Abstract
An improved optical fiber gyroscope is provided to determine the angular velocity of an optical system. A beam of light emitted from a coherent light source are split into first and second light components. The first light component is further split into third and fourth light components while the second light component is further split into fifth and sixth components. The third and fifth light components are passed through a coil-like optical fiber in opposite directions to each other while the fourth and sixth light components are passed through an optical modulator in opposite directions to each other. The third and fourth light components are made to be interfered in a photodetector while the fifth and sixth light components are made to be interfered in another photodetector. From the outputs of the photodetectors, the above angular velocity is determined.
