Fiber optic gyroscope for detecting angular velocity of rotation using equivalent time sampling

摘要: A phase-modulated fiber optic gyroscope comprises a signal generating section, photoelectric converter section and processing section. The includes light source, an optical path for propagating from the source clockwise counterclockwise, phase modulator modulating through path. converts received into electric signal. derives direction of rotation velocity analog-to-digital converting digital signal, processor carrying out angle calculations based on converter.
