Device.
Background technique
Fiber Fabry-Pérot cavity detects measured using simple optical fiber, using beam interference.When light reaches two instead
It penetrates behind face and generates two beam reflected lights respectively, this two beams reflected light generates interference after meeting.When interference cavity chamber personal attendant is measured variation
When, the phase difference of two reflected lights changes, and then measures.It is a kind of sensor widely researched and developed at present.
The optical fiber of external cavity type Fabry-Perot sensor Fundamentals of Welding figure two well cuttings as shown in Figure 1: is to through capillary
In glass tube.It needs to carry out welding or bonding to left and right two o'clock.In the prior art mainly using optical fiber splicer welding or
Use optics glue sticking.Using the method for optical fiber splicer welding, loss is small, reproducible, but complicated for operation, and about
The positioning of two solder joints is not accomplished to be accurately positioned, and the chamber length of Fabry-Perot-type cavity cannot be controlled accurately；Using cold joint method, i.e.,
The optics glue sticking similar in optical index and fibre core, this method is not easy to collimate, and poor reliability.In addition the end face of optical fiber away from
The bad determination of repeatability from (i.e. Fabry-Perot-type cavity is long), it is complicated for operation.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of bipolar electrode fiber Fabry-Pérot cavities

Fig. 2 is schematic structural view of the invention.
Fig. 3 is top view of the invention.
Specific embodiment
It elaborates below to the embodiment of the present invention, the present embodiment carries out under the premise of the technical scheme of the present invention
Implement, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to following implementation
Example.
As shown in Fig. 2 to 3, a kind of bipolar electrode fiber Fabry-Pérot cavity fusion splicing devices, including bracket 2, fiber clamp 4,
Welding electrode 5 and optical amplification system 3, it is characterised in that: the U-shaped structure of the bracket 2, the two-arm top of bracket 2 are provided with
Fiber clamp 4, the welding electrode 5 have two pairs, and 2 bottom of bracket is provided with V-groove 1, is provided with weldering at the top of the V-groove 1
Chamber 12 is connect, the welding electrode 5 is directed toward welding chamber 12.Usually when welding 6 Fabry-Perot-type cavity 8 of optical fiber, need successively to a left side
Right two solder joints are subjected to, and are only capable of welding a solder joint every time using existing 6 welder of optical fiber, be needed
The taking-up of glass capillary 7 is again subjected to second solder joint after first time welds, such trivial operations, it is easy to
It causes the solder joint being welded to be broken, and can not accomplish being precisely controlled for distance between two solder joints.It is provided by the present invention
Scheme is hit by the way that two butt welding contacts are arranged, and can be welded two solder joints in left and right simultaneously, be realized that single stepping carries out two solder joints
Welding, substantially increases welding efficiency, while ensure that welding quality, while yield rate improves, 6 method of optical fiber welded
Fabry-Perot-type cavity 8 obtains length and can be well controlled, and reproducible.V-shaped groove makes it for placing glass capillary 7
Position is fixed, and the progress of welding is facilitated, and setting welding chamber 12 can facilitate the end of welding electrode 5 direct on V-shaped groove
It is directed toward position to be welded, is rapidly performed by welding smoothly, while the setting for welding chamber 12 also facilitates optics to prevent big system
Display is amplified to welding position, guarantees welding quality and yield rate.
There are two the settings of welding chamber 12, is provided with supporting walls 13, two pairs of welderings between two welding chambers 12
Receiving electrode 5 is respectively directed to different welding chambers 12.The tube wall of glass capillary 7 is very thin, and external force again is easy to after putting on optical fiber 6
It occurs bending and deformation under effect, to influence yield rate, is divided into two for chamber 12 is welded by setting supporting walls 13, exists in this way
The middle position of glass capillary 7 can be supported the support of wall 13, to guarantee that it is in normal morphology.
Linear slider 21 is provided between the fiber clamp 4 and bracket 2.In 4 bottom of fiber clamp, linear slider is set
21, so that 6 position of optical fiber of the right and left is able to carry out and is adjusted flexibly, to carry out to the length of Fabry-Perot-type cavity 8 accurate
Control cooperates optics display portion, makes 6 end face of optical fiber and capillary by the push driving mechanism connecting with each fiber clamp 4
The welding position of glass tube 7 can obtain accurately controlling very much.
The slot bottom of the V-groove 1 is provided with the sucker 11 being controlled to a vacuum pump, and the sucker 11 is for fixing capillary glass
The position of pipe 7.It is limited to the length of glass capillary 7, fixture, which is arranged, to fix glass capillary 7 can block the portion for needing to weld
Position, to make welding that can not be normally carried out, being not provided with fixture can make its position that cannot fix again, easily send out in the welding process
Raw displacement, it is not up to standard to lead to weld unsuccessful or welding quality, greatly promotes rejection rate, makes V-arrangement by the setting of sucker 11
The slot bottom of slot generates negative pressure and plays good fixed function so that glass capillary 7 is firmly sucked, while such setting
Count not will cause entirely blocks, and will not influence welding.
The above is merely preferred embodiments of the present invention, be not intended to limit the invention, it is all in spirit of the invention and
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within principle.
