Title:
光学ファイバジャイロスコープ用の耐環境に優れた偏光解消素子
Document Type and Number:
Japanese Patent JP4684419
Kind Code:
B2
Abstract:
A design for an environmentally robust fiber depolarizer for a fiber optic gyroscope is disclosed. The design comprises; substantially a clockwise propagating leg and a counterclockwise propagating leg, distally coupled at opposite ends of a gyroscope sensing coil, said depolarizer fiber leg wound in a that is rotation insensitive pattern and that is also a symmetrical winding pattern. Moreover, axial, radial and embedded sensing coil mounting methods for the fiber depolarizer to reduce the depolarizer sensitivity to thermal variations are also disclosed. Specific attention to the design of the fiber depolarizer of a gyroscope provides enhanced immunity to the stress of environmental variation.
