Description
Technical field
The present invention relates to be used in the optical image technology in the fused fiber splice field, particularly optical fiber splicer the optical imaging device of optical fiber align, detection.
Background technology
Quartz glass optical fiber is made up of quartzy core and the quartzy covering that is formed on around the core, and the surrounding layer that is made of plastics wraps up reinforcement protection.Light transmits in fiber core.This type optical fiber is widely used in the fields such as optical signal transmission.For making light signal effective certain distance of transmission in optical fiber, the optical fiber that needs to lack relatively link together and added losses as far as possible little; Little light signal loss transmission can be in the cylindrical desirable fibre core at one and realize.During the optical fiber splicer welding optic fibre, be by the optical microphotograph camera system, obtain two alignment errors that need butt joint optical fiber, adjust this error to allowed band, the employing electrical discharge arc heats, and makes it close mutually, fuses to be qualified integral body.Whether existing optical fiber splicer is generally aimed at from the two-dimensional direction detection fiber.The X, Y direction light source irradiation that promptly adopt quadrature be at the optical fiber end points place that needs connect, and come focal imaging by two groups of optical microphotograph camera systems; Adjust the motion of optical microphotograph camera system by mechanical driving mechanism, make video camera obtain the optical fiber sharp image; Judge the alignment error of two optical fiber in view of the above.The characteristics of this type of optical fiber splicer are made up of two road optical microphotograph imaging systems, and need motion to make two road optical fiber micro imaging systems arrive the working position, make imaging fiber clear.The heat sealing machine of this optical microphotograph camera system needs the optical microphotograph camera system to carry out view finding, focus movement, mechanism's complexity, poor stability.Though other has a kind of optical fiber splicer only to use one group of optical microphotograph imaging system, when it obtains one of them direction image, need between two sparking electrodes, increase reflective mirror, wherein one road light reflexes in the optical microphotograph imaging system; The optical microphotograph imaging system need be done corresponding adjustment movement simultaneously, makes it arrive 2 different working positions; Because reflective mirror has blocked sparking electrode, need to remove reflective mirror before welding simultaneously, this direction image disappears.Because above-mentioned structure and principle, this system can't obtain the image of 2 directions simultaneously.The characteristics of this kind optical fiber splicer are: adopt X, Y two-way light source, though only use one group of optical microphotograph imaging system, need complicated adjustment motion.
Summary of the invention
Purpose of the present invention is exactly a kind of single-lens imaging device for optical fiber fusion splicer that proposes for the complex structure that the optical imaging device that overcomes in the prior art exists, poor stability.
To achieve these goals, the present invention has adopted following technical scheme:
Single-lens imaging device for optical fiber fusion splicer, it comprises two road at an angle incident light source, a pair of welding electrode, an optical microphotograph imaging device and camera heads, it is characterized in that: a cover light reflection converging device is set between described welding electrode and the optical microphotograph imaging device, it converges two road at an angle incident lights, and the light that will converge is incident to the optical microphotograph imaging device.
As best mode, two road incident lights in the single-lens imaging device for optical fiber fusion splicer are vertical mutually, one cover optical reflection converging device is set between described welding electrode and the optical microphotograph imaging device, it converges two road orthogonal incident lights, and the light that will converge is incident to the imaging of optical microphotograph imaging device.
According to above-mentioned best-of-breed technology scheme, can have and followingly specifically optimize structure:

3, described optical reflection converging device is made up of two polygon prisms (combination polygon prism), incident light in each polygon prism through converging behind two secondary reflections and being 135 ° with former incident angle.
Liquid lens described in the technique scheme, be known product, now illustrate that with the Electrowetting type liquid lens liquid lens is two kinds of different and immiscible liquid of refractive index, a kind of is conductive aqueous solution, and another kind is nonconducting silicon ketone oil solution.And two kinds of liquid are encapsulated in all transparent cylindrical pressure vessel in two sides.Chamber wall has been done the hydrophobicity processing.Therefore aqueous solution can be cheese and accumulates in the container center part, will form convex curved surface between aqueous solution and the silicon ketone oil, changes curvature and can focus by applying controlled electric signal.Promptly realize focusing (focusing) effect.
As can be seen from the above technical solutions, essence of the present invention is: by a cover optical secondary reflection converging device, be to receive image by a microscopic imaging device with two different directions video conversion, realized the optical fiber align error-detecting of both direction.Here, the optical reflection converging device that is adopted reaches the conversion of two optical imagery directions.What need supplementary notes is:
The effect of a, two reflective mirrors:,, changed direction of light by 2 reflective mirrors with the optical fiber image of transmission.
B, prismatic action are: will reflect the light that converges through reflective mirror, and be incident in a microscope camera system.Only adopt an optical microphotograph camera head just can obtain the optical fiber image of 2 directions simultaneously.And do not need moving of system.The present invention that Here it is is different from one of different place of existing optical fiber splicer.
C, polygon prism (combination polygon prism) effect are: both had the effect of two reflective mirrors, the light that possesses prism simultaneously again converges effect.
Second characteristic of the present invention are: used liquid lens in the optical microphotograph imaging system, the effect of liquid lens is, by applying the curvature that controlled electric signal changes liquid lens, make liquid lens play the effect of focusing, and need not to make the optical microphotograph camera system to move, reach the purpose of focusing, compare, cancelled the complex mechanism that drives the motion of optical microphotograph camera system with traditional heat sealing machine.
Owing to adopted technique scheme, made the present invention have following advantage:
1, only uses one group of optical microphotograph imaging and camera system, make simple in structure;
2, use a cover optical secondary reflection converging device that the both direction image is incided same microscope camera system, and do not need moving of system, can finish the detection of optical fiber align easily, and then improve fused fiber splice quality, performance and cost.
