Abstract

It is wave-guide structure optical gyro and its process method realized with organic polymer materials and substitutes the traditional wave-guide fiber with the organic polymer materials to manufacture the wave-guide structure optics peg-top, which comprises intervention, and resonance wave-guide structure optics gyro. Its process steps are the following: a to coat the organic polymer materials solvent on the underlay through the rotation cover method and to make single or multiple layers organic polymer thin film; b to make mask plate with metal materials according to the pre-designed ring wave-guide needed; c to make the ring wave-guide by laser etching method or ultra-violet bleaching method to form the wave-guide structure gyro.

Description

technical field [0001] The invention proposes an optical gyroscope realization scheme of a waveguide structure, in particular to an optical gyroscope realizing an optical waveguide structure with an organic polymer material. Background technique [0002] The optical gyroscope is a new type of photoelectric gyroscope based on the Sagnac effect. The Sagnac effect is a general correlation effect of the propagating light in the closed-loop optical path that rotates relative to the inertial space. After going through the same optical path and traveling in opposite directions, they return to the beam splitting point in the same phase. If there is a rotational angular velocity relative to the inertial space around the axis perpendicular to the plane where the optical path is located, the optical paths traveled by the light beams propagating in the forward and reverse directions are different, resulting in an optical path difference. Theoretically, it can...
