Webfiber optic gyroscopes where long lengths and small diameter coils are a requirement. OFS has been manufacturing polarization-maintaining optical fibers since the early 90‘s when TruePhase® PM Optical Fibers were introduced for telecommunications applications. GyroSil Rad-Hard PM Optical Fiber is a new addition to the A fibre-optic gyroscope (FOG) senses changes in orientation using the Sagnac effect, thus performing the function of a mechanical gyroscope. However its principle of operation is instead based on the interference of light which has passed through a coil of optical fibre, which can be as long as 5 … See more Two beams from a laser are injected into the same fibre but in opposite directions. Due to the Sagnac effect, the beam travelling against the rotation experiences a slightly shorter path delay than the other beam. The resulting … See more A FOG provides extremely precise rotational rate information, in part because of its lack of cross-axis sensitivity to vibration, … See more • Attitude and Heading Reference System • Hemispherical resonator gyroscope • Inertial measurement unit • Inertial navigation See more Like all other gyroscope technologies and depending on detailed FOG design, FOGs may require initial calibration (determining which indication corresponds to zero angular velocity).
