Technical field
The present invention relates to a kind of the coil that uses in the optical fibre gyro be carried out the device that gluing and gluing are used.
Background technology
Optical fibre gyro is a kind of optical fiber angular-rate sensor based on the Sagnac effect, and it is with a wide range of applications, and under the environment that difference is used, optical fibre gyro should have high reliability, and the index of one of its performance is exactly a vibration resistance.Though optical fibre gyro has the advantage of antivibration for the gyro of other type, in use also manifest the influence that vibration environment produces the optical fibre gyro precision.One of its problem is the not firm of fiber optic coils, when optical fiber is wrapped on the fiber optic loop by same direction, to watch from macroscopic view, the optical fiber coiling gets tight especially, but watch from microcosmic, all have certain clearance between optical fiber and the optical fiber and between optical fiber and the ring.Optical fiber does not have constraint or retrains insufficiently, produces displacement, distortion etc. in vibration, finally influences the normal output of optical fibre gyro.
In order to improve the fiber optic loop resistance to shock, when being winding optical fiber ring, present way applies one deck glue at optical fiber surface.From reality around loops fruit, though gluing can improve the resistance to shock of fiber optic loop, if coating technique is improper, not only the antivibration effect is bad, also can influence another important parameter of fiber optic loop---polarization cross-talk.Mainly show following aspect around encircling the influence of gluing to fiber optic loop:
(1) influence of glue-spread: glue-spread is less, and the antivibration ability of fiber optic loop is obviously lower; When glue-spread was big, vibration performance was good, but that the polarization cross-talk of fiber optic loop descends is a lot, even unqualified (this gluing be " brush coating " mode, to the glue amount how much uncontrollable).
(2) influence of the coating uniformity: vibration performance and polarization cross-talk are all had a direct impact, neither qualified when serious.
(3) influence of the hardness of cured glue: gluing does not solidify or solidifies not exclusively, and vibration does not pass a test; But when hardness is big after solidifying, influence the polarization cross-talk of fiber optic loop again.
For these reasons, in the winding process of light ring, must control coating and coating quality with glue, therefore, the inventor of present patent application sticks with glue through experimental demonstration that agent is fixed when twining between with optical fiber and optical fiber to be one, adhesive just can be filled in the space between these optical fiber and the optical fiber like this, under condition of cure, utilize the bonding force of glue, can make optical fiber and optical fiber and optical fiber and fiber optic loop be linked to be an integral body, so just can guarantee that coil has good robustness, reduce the influence of vibration environment optical fibre gyro.
