Description
Technical field
The present invention relates to the device of the complicated winding process of optical fiber, especially relate to a kind of coiling device that adopts the fine ring that depolarizes of single-mode fiber.
Background technology
Single-mode fiber is actual two kinds of polarization modes.These two kinds of patterns almost are degeneracys, exist remaining birefringence, have changed the propagation polarization state of light.In ring interferometer, a given position, the polarization state difference of two beam reversal's wave travels, because birefringence, the refractive index of experience is also also incomplete same, thereby produces the phase differential of a parasitism at output terminal.This has just destroyed for the very important reciprocity condition of optical fibre gyro.Therefore, traditional optical fibre gyro system all can be placed at public reciprocity port and remove inclined to one side device, eliminates parasitic phase differential as far as possible.But going inclined to one side device to be coupling in the light path, brought luminous energy loss and new error again, made the stability decreases of system.
If the employing polarization maintaining optical fibre, gyrosystem does not just need inclined to one side device, because polarization maintaining optical fibre has only a kind of polarization mode, can not produce the problems referred to above.Yet, the costing an arm and a leg of polarization maintaining optical fibre, this is very unfavorable for large-scale production.
Summary of the invention
The object of the present invention is to provide a kind of coiling device that adopts the fine ring that depolarizes of single-mode fiber, its made single-mode fiber ring self has the bias energy, needn't add the function that inclined to one side device just can realize going in the traditional fiber gyro inclined to one side device and two Primary Components of fiber optic loop.
The technical solution adopted for the present invention to solve the technical problems is:
Both sides on the chassis are installed first supporter and second supporter respectively, first rotating shaft is installed on the first supporter leading flank, first rotating shaft is rotated by first driven by motor that is contained on first supporter, first baffle plate is housed in first rotating shaft and treats around ring, one end of connecting rod is fixedlyed connected with first rotating shaft, on the other end of connecting rod stationary shaft is housed, second baffle and first preparation ring are housed on the stationary shaft, second supporter is installed second rotating shaft on the side of first supporter, second rotating shaft is rotated by second driven by motor that is contained on second supporter, second rotating shaft is connected with the galianconism of L bracket, the 3rd rotating shaft is installed on L bracket long-armed, in the 3rd rotating shaft the 3rd baffle plate and second preparation ring is housed, on the chassis between first supporter and second supporter horizontal guide rail is housed, slide block with the 3rd motor can slide on horizontal guide rail, on the support of slide block pulley is housed, and treats to be located on the same line around ring and second preparation ring.
The beneficial effect that the present invention has is:
This device makes single-mode fiber limit in winding process reverse around the limit, thereby coiling goes out to have the single-mode fiber ring of bias energy.This just makes in the optical fibre gyro system needn't add inclined to one side device, has simplified system, has reduced the luminous energy loss and the measuring error of gyrosystem.It had both improved the performance of system, had reduced the cost of making again.
