ABSTRACT:
A depolarized fiber optic gyroscope with a detector for detecting a rotat about an axis of rotation and a method therefor is disclosed. The gyroscope includes a depolarized light source for generating the depolarized light; a gyro coil for conducting depolarized light about the axis of rotation, the gyro coil including a coil of a non-polarization preserving fiber having first and second ends; a depolarizer with first and second ports for eliminating birefringence induced scale factor variations caused by the non-polarization preserving fiber, the first port of the depolarizer being coupled to the first end of the gyro coil; and a coupler device for coupling the second end of the gyro coil, the second port of the depolarizer, the detector and the depolarized light source, without utilizing a polarizer.
