Description
Technical field
The present invention relates to a kind of detection method, particularly to a kind of conical fiber conehead detection device and detection judgement side
Method.
Background technology
Conical fiber may be used for sensing, the fields such as scanning imagery of marching into the arena.Use photosensitive polymerization method at silica fibre end face
Making conical fiber, optical fiber is the SMF-28e single-mode fiber of Corning Incorporated.Preparation flow is: (a) is by polymer monomer, dyestuff
Sensitizer and solvent mix with certain proportion；B silica fibre smooth for ends cutting is placed in this mixed liquor placement by () certain
Taking out after time, under van der Waals interaction, fiber end face has a certain amount of mixed solution；C wavelength is the laser of 532nm by ()
It is coupled into optical fiber by end coupling method；D () fiber exit end is under the effect of Gaussian beam, monomer polymerization forms taper
Optical fiber.The conical fiber of preparation is as shown in Figure 1.
Conical fiber applies fluorescence indicator by czochralski method, can be dissolved oxygen by fluorescent quenching method dense
Degree, explosive concentration and concentration of metal ions etc. detect.But it is during actual experiment, quick when conical fiber is coated
Sense material and put into the measured matter of variable concentrations, all can due to the improper conical fiber drop that causes of operation, but taper
Fibre diameter only has nanometer to micron dimension, and length is also micron dimension, it is impossible to judge conical fiber whether drop by naked eyes.
The present invention relates to the determination methods of a kind of conical fiber conehead presence or absence.
Summary of the invention
The present invention be directed to current conical fiber when doing sensing head, optical taper whether cannot use by drop in operation
The problem that naked eyes judge, it is proposed that a kind of conical fiber conehead detection device and detection determination methods, it is not necessary to use microscope
In instrument, quickly carry out detection and judge.
The technical scheme is that a kind of conical fiber conehead detection device, including laser instrument, condenser lens, centre
The blank screen having a diameter of 1cm hole, the adjustment frame shelving detected conical fiber and white film viewing screen, the laser of laser emitting
First pass through condenser lens and focus on the hole of blank screen, being optically coupled in detected conical fiber fibre core by hole, detected
The light of conical fiber outgoing shines and forms hot spot on white film viewing screen.
The detection determination methods of described conical fiber conehead detection device, exists by observing detected conical fiber coupling light
Hot spot on white film viewing screen carries out detection and judges: if the hot spot on white film viewing screen is as annular, i.e. middle is speck, around
Having a circle Crape ring, outmost turns is bright ring, and now the conehead of conical fiber exists；If the hot spot on film viewing screen is a speck,
The then conehead of conical fiber drop.
The beneficial effects of the present invention is: conical fiber conehead of the present invention detection device and detection determination methods, Ke Yi
During carrying out material concentration detection, it is not necessary to conical fiber is taken down, not by microscopical situation from adjustment frame
Under, directly judge whether conical fiber is deteriorated by conical fiber emergent light spot.This determination methods has saving experiment
Time, it is not necessary to the advantage of the instruments such as microscope.
Accompanying drawing explanation
Fig. 1 is the conical fiber termination figure under 40 power microscopes；
Fig. 2 is conical fiber conehead structure of the detecting device figure of the present invention.
Detailed description of the invention
Conical fiber conehead structure of the detecting device figure as shown in Figure 2, has directly including laser instrument 1, condenser lens 2, centre
Footpath is the blank screen 3 in 1cm hole, the adjustment frame 6 shelving detected conical fiber 4 and white film viewing screen 5, the laser of laser instrument 1 outgoing
First pass through condenser lens 2 and focus on the hole of blank screen 3, being optically coupled in detected conical fiber 4 fibre core by hole, tested
The light surveying conical fiber 4 outgoing shines formation hot spot on white film viewing screen 5.Blank screen 3 can stop ambient stray be optically coupled into by
Detection conical fiber 4, the detected conical fiber of regulation 4 adjustment frame 6 below, make condenser lens 2 shoot laser be coupled to taper
In fiber core.
During carrying out material concentration detection, it is not necessary to detected conical fiber 4 is taken down, directly from adjustment frame 6
Connecing and be energized to laser instrument 1, the hot spot being coupling on screen by observing detected conical fiber 4 judges that the conehead of conical fiber is in reality
Whether drop during testing.If the hot spot on film viewing screen is annular, i.e. middle is speck, around has a circle Crape ring, outmost turns
For bright ring, now the conehead of conical fiber exists.If the hot spot on film viewing screen is a speck, then the conehead of conical fiber is
Through drop during testing.Laser instrument output light all can realize judging at visible light wave range.
Claims (2)
1. a conical fiber conehead detection device, it is characterised in that include that laser instrument, condenser lens, centre have a diameter of
The blank screen in 1cm hole, the adjustment frame shelving detected conical fiber and white film viewing screen, the laser of laser emitting first passes through focusing
Lens focus is on the hole of blank screen, and being optically coupled in detected conical fiber fibre core by hole, detected conical fiber goes out
The light penetrated shines and forms hot spot on white film viewing screen.
The detection determination methods of conical fiber conehead detection device the most according to claim 1, it is characterised in that by observing
