Description
Technical field
The present invention relates to a kind of optical fibre spectrum measuring devices in electric field, particularly a kind of and can the optical fibre spectrum measuring devices of added electric field or electric current.
Background technology
The close prior art of basic invention is Chinese patent " fiber Raman spectrometer " patent No. 99127494.6, and the sample chamber of this device is that the end socket installed additional by one section of liquid-core optical fibre and two ends is formed.Its device is made up of Embedding Materials such as end socket overcoat, glass window, sample injection tube, indium or tin.End socket overcoat is a glass tube and the centre shape with ball; One end of glass tube is closed as glass window with glass, seals after the other end then inserts hollow optic fibre with indium tin Embedding Material; Sample injection tube is contained on the glass ball of end socket overcoat.After fluid to be measured sample is injected sample chamber, exciting light is propagated in optical fiber, constantly excites fluid sample again, the Raman spectrum produced or fluorescence spectrum etc. are also propagated in a fiber, its intensity is constantly accumulated, and is finally exported from the glass window the end socket of the optical fiber other end by " amplification ".Therefore the spectral intensity such as Raman spectrum, fluorescence spectrum, absorption spectrum adopting sample fiber room to obtain increases 10 than adopting common sample room
3doubly left and right.But this sample fiber room can not be used for measuring the various spectrum along liquid core light transmitting fiber (optical waveguide) in the electric field in optical fiber direction.
Summary of the invention
The object of this invention is to provide one on the basis of existing technology, optical fiber end socket is improved, neither affect the result of use of former optical fiber end socket, can be used for again measuring the various spectrum of liquid core light transmitting fiber (optical waveguide) in electric field.
To achieve these goals, technical scheme of the present invention is as follows:
Respectively install an optical fiber end socket additional at the two ends of hollow optic fibre, the end socket overcoat of optical fiber end socket is the shape that a glass tube and Intermediate Gray have georama; One end of glass tube is closed as glass window with glass, seals after the other end then inserts hollow optic fibre with the Embedding Material such as indium, tin; Sample injection tube is contained on the glass ball of end socket overcoat, and on the glass ball of two end socket overcoats, electrode is equipped with in sealing respectively.
Described electrode is metallic conductor, and wherein half section is inserted in the glass ball of end socket overcoat, another half section outside the glass ball of end socket overcoat, and binding post is housed.Such electrode fills 1 ~ 3 on an optical fiber end socket.
During use, in optical fiber end socket, testing sample or the liquid containing testing sample is injected by sample injection tube, testing sample enters hollow optic fibre by the space of glass window and hollow optic fibre termination, shutoff sample injection tube after filling fluid sample, whole system is sealed, and hollow optic fibre forms liquid-core optical fibre.Now, hollow optic fibre (kapillary) is to the refractive index of the refractive index of light higher than testing sample.Allow one end of the incident liquid-core optical fibre of laser, the other end measures " amplification " spectrum such as its absorption spectrum, fluorescence spectrum, Raman spectrum.If switch on power on the electrode of two optical fiber end sockets (added electric field), then for measuring the spectrum such as absorption spectrum, fluorescence spectrum, Raman spectrum of the testing sample under electric field or the function of current, and various spectrum is with the situation of electric field or curent change.
The present invention is owing to being added with electrode at liquid-core optical fibre two ends, can at optical fiber two ends added electric field in spectral measurement, make to produce electric field or electric current in liquid-core optical fibre, thus testing sample some physics under electric field or the function of current, chemistry, biological function and change can be measured.

Embodiment
Embodiment 1 composition graphs is described structure of the present invention.In figure, 1 is hollow optic fibre, and 2 is electrode, and 3 is end socket overcoat, and 4 is the georama part of end socket, and 5 is glass window, and 6 is sample injection tube, and 7 is the Embedding Material such as indium, tin.End socket overcoat 3 comprises a glass tube and Intermediate Gray has hollow rounded portion 4, and one end of glass tube is sealed by glass window 5, and the other end pours between glass tube and hollow optic fibre 1 with the Embedding Material such as indium, tin 7 and makes it to seal after inserting hollow optic fibre 1.The termination of hollow optic fibre 1 is close to glass window 5.Sample injection tube 6 is contained in georama part 4, can be mutually vertical with the glass tube of end socket overcoat 3.Half section of electrode 2 is inserted in georama part 4, and another half section is exposed outside georama part 4, and binding post is housed.
Optical fiber end socket is by two, and the two ends of hollow optic fibre 1 can be sealed, be inject window by injecting light-struck glass window 5, and the glass window 5 of hollow optic fibre 1 other end is exit window, treats light-metering in this reception.
In optical fiber end socket and hollow optic fibre 1, inject fluid sample by sample injection tube 6 and form liquid-core optical fibre; The electrode of liquid-core optical fibre two ends end socket switches on power, testing sample some physics under electric field or the function of current, chemistry, biological function and change can be measured.
Embodiment 2 example cites an actual example-and measuring tempeature is on the impact of photoluminescence spectrum intensity.Fluid sample is made up of pyridine, potassium sulfate and distilled water, is filled with in device of the present invention, forms the liquid-core optical fibre of long 123cm.Now, fluid sample refractive index is 1.50, optical fibre refractivity is that 1.46. optical fiber insulating material is packed, with fluid sample box external temperature in two thermocouple measurement optical fiber, with the fine one end of He-Ne laser beam incident, the emergent light of the other end injects double grating monochromator after lens focus, receives fluorescence signal, by photon counter receiving spectrum intensity (photon number) with the photomultiplier of cooling.Two electrodes connect DC high-voltage power supply, current stabilization a period of time, make after inside and outside optical fiber, two thermopair measured temperatures are all stablized, and read fluid temperature value in optical fiber, take out thermopair, measure photoluminescence spectrum intensity.Process the experimental data of repetitive measurement, the conclusion obtained is, the change that the photoluminescence spectrum intensity that optical fiber receives is sensitive with the change of electric current; Strength of current increases, and photoluminescence spectrum intensity reduces, and strength of current reduces, and photoluminescence spectrum intensity increases; Experimental result and theory calculate well meet.
