Fiber Optic Coils for Gyroscopes

Name: Fiber Optic Coils for Gyroscopes
Brand: OZ Optics
Availability: InStock

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.
