Abstract

The invention discloses an optical fiber untwisting device. An optical fiber guided out of an optical fiber traction assembly passes through an optical fiber twisting detecting unit, an optical fiber winding and clamping assembly and an optical fiber untwisting assembly which are arranged in sequence and is wound around the interior a fiber winding disc in the optical fiber untwisting assembly. The optical fiber untwisting assembly comprises a rotary driving motor, a transmission mechanism and the fiber winding disc. The rotary driving motor is connected with an angle sensor and rotates according to a feedback signal given by the angle sensor. The optical fiber winding and clamping assembly is driven by the transmission mechanism to rotate synchronously and connected with the transmission mechanism through a flange face. The optical untwisting device can overall untwist the whole long optical fiber, torsional stress existing in the optical fiber is reduced, the magnetic sensitivity problem of a fiber-optic gyroscope is solved, and the precision of the fiber-optic gyroscope is improved. In addition, by means of the optical fiber untwisting technology, the influence of eccentricity of an insulated single wire on characteristic impedance can be eliminated, and the requirement for the concentricity of the insulated single wire can be reduced.

Description
