Fiber Optic Coils for Gyroscopes
Description
The Fiber Optic Coils for Gyroscopes are crucial components used in fiber optic gyroscopes, particularly in applications such as autonomous vehicles and military systems. These coils utilize stress-induced high-birefringence polarization-maintaining (PM) single-mode fiber to achieve exceptional performance. With the Sagnac effect as the foundation, the phase difference generated by two counter-propagating optical signals within the fiber coil is directly proportional to the rotation rate experienced by the coil.
OZ-Optics specializes in the design, manufacturing, and testing of customized fiber coils, employing symmetrical winding methods to minimize thermally induced bias errors. These coils offer high performance, stability, reliability, and low polarization crosstalk, making them ideal for various gyroscope applications.

Frequently Asked Questions
Fiber Optic Coils for Gyroscopes are crucial components used in fiber optic gyroscopes, particularly in applications such as autonomous vehicles and military systems.
Stress-induced high-birefringence polarization-maintaining (PM) single-mode fiber offers low polarization crosstalk, preventing signal fading and ensuring high performance.
The phase difference generated by two counter-propagating optical signals within the fiber coil, based on the Sagnac effect, is directly proportional to the rotation rate experienced by the coil, allowing for accurate gyroscopic measurements.
These fiber coils utilize symmetrical winding methods, such as quadrupole winding, to minimize thermally induced bias errors known as the Shupe effect.
These fiber optic coils are suitable for applications such as fiber optic gyroscopes for navigation and motion sensing, autonomous vehicles for improved positioning and navigation, fiber optic delay lines for signal processing and time-delay applications, and fiber optic current sensing for accurate current measurements.
