Increase, wait a kind of based on biologic sensor for fast travelling waves of optical fibre detect Listeria Monocytogenes method foundation [J] in
State's Laboratory Diagnosis, 2014 (7):1045-1047.), volatile organic matter detection (document 4. in celery forever, Li Xuejin, Ou Zhilong,
Deng volatile organic compound detection devices of the based on optical fiber evanescent field:CN, CN203443888U [P] .2014.) in terms of.In order to
Strengthen the interaction of fibre core surface evanscent field and medium, it is necessary to remove part fiber covering to improve transducer sensitivity.Go
Except the method for covering mainly has two kinds：Etch and polishing.Etch is referred mainly to using hydrofluoric acid solution by controlling its dense
Degree and etching time are so as to produce the sensor fibre of different-diameter, and this method is less demanding to experiment condition, and has into
This low, the advantages of gained optical fiber surface is smooth.
Most of fiber optical corrosive method proposed at present can only corrode optical fiber from side, for example, fix optical fiber vertically
Corrode (document 5.A.Iadicicco.S, Campopiano, A.Cutolo, et al.Nonuniform in plastic tube
thinned fiber Bragg gratings for simultaneous refractive index and
temperature measurements[J],IEEE Photonics Technology Letters,2005,17(7):
1495-1497), or by optical fiber one end level it is put into corrosion device that (history of document 6. is big, Fang Qiang, and Qi Liang one kind realizes optical fiber
The device of surface smooth taper corrosion, CN 203938601U [P] .2014.).This forms of corrosion can not be met in some cases
Corrode being actually needed for a certain section of optical fiber, another aspect hydrofluoric acid has hypertoxic and volatile, in use probably
Operating personnel are damaged, the optical fiber after corroding in addition is more crisp, is easily broken, how to keep optical fiber integrality to be also one has
To be solved the problem of.
The content of the invention
The device of the present invention improves the shortcomings of the prior art, and there is provided a kind of simple in construction, operation side
Just fiber optical corrosive device.
The technical solution adopted by the present invention is：
