Fiber optic gyroscope is an instrument that uses the principle of slit interference and measures phase changes to detect angular velocity or angular displacement. It mainly consists of laser light source, beam splitter, optical fiber loop and detector.
The optical gyroscope is a new all-solid-state inertial device that uses the Sagnac effect to measure the rotation angular rate. Take Ericco's low-cost fiber optic gyroscope ER-FOG-50 (0.2~2.0º/h) as an example. Compared with other traditional mechanical gyroscopes, it has the following advantages:
1. It is an all-solid-state gyroscope, with no rotating parts and friction parts inside.
2. Stability, strong drop resistance, no consumable parts, and long life. Fiber optic gyroscopes can operate for a long time in high temperature, high pressure, shock and vibration environments in coal mines and petroleum logging fields. However, the mechanical gyroscope's internal bearings are impacted, which also affects the life and operation of the gyroscope. This is also the main reason why most people now choose fiber optic gyroscopes.
3. Small size. The size of ER-FOG-05 is Φ50mm×38mm, which is suitable for customers with limited working environment.
4. In addition, fiber optic gyroscopes also overcome the fatal shortcomings of ring laser gyroscopes such as high cost and latch-up phenomenon.
