Detailed description of the invention
Fig. 1 is a kind of showing for the production method of device for increasing fiber spectrometer signal strength provided by the embodiments of the present application
It is intended to.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
A kind of production method for the device increasing fiber spectrometer signal strength, comprising:
One end of 105 microns of optical fiber of four array arrangements is coupled with one end of 200 microns of optical fiber；

The production method of the device of above-mentioned increase fiber spectrometer signal strength, the device can make compared with the light letter in coarse optical fiber
It number is coupled into thinner optical fiber, improves the energy density of fiber end face, to keep the light entered in spectrometer more, mention
The intensity of spectral signal is risen.
A kind of increase fiber spectrometer of the production method production of the device of above-mentioned increase fiber spectrometer signal strength
The device of signal strength.
A kind of fiber spectrometer, the device of the increase fiber spectrometer signal strength including above-mentioned production.
Fiber spectrometer it is general by optical fiber interface, slit, spectro-grating, reflecting mirror, focus spherical mirror, CCD etc. zero
Part composition, wherein optical fiber interface is connected with optical fiber, makes signal light by intelligent acess into spectrometer, slit makes fibre optical transmission
Light only has sub-fraction to penetrate into spectrometer, and the width of slit determines the optical resolution of spectrometer, and slit is wider, light
The optical resolution of spectrometer is lower, and the light into spectrometer is more, and the sensitivity of spectrometer is also higher.Slit is narrower, spectrometer
Optical fiber resolution ratio it is higher, the light into spectrometer is also fewer, and the sensitivity of spectrometer is also corresponding lower.It can be seen that spectrum
The slit width of instrument affects the optical resolution and sensitivity of spectrometer, we are it is of course desirable that the optical resolution of spectrometer is got over
High better, the higher the better for sensitivity, however the two characteristics contradiction each other, can not get both.
In order to which in the case where not changing spectrometer, acquisition intensity is higher, the higher spectral signal of signal-to-noise ratio, we are designed
A kind of device, the device can make to be coupled into thinner optical fiber compared with the optical signal in coarse optical fiber, make the energy of fiber end face
Density improves, to keep the light entered in spectrometer more, improves the intensity of spectral signal.For example, incident light spectrometer
Fiber cores to pass through be 200um, the slit of fiber spectrometer is 20um, it is assumed that light in the case where fiber end face is to be uniformly distributed,
There are about 12% light to enter spectrometer.If by the optical fiber for being optically coupled into 100um in the optical fiber of 200um, there are about
25% light enters spectrometer, is twice of 200um fiber-optic signal intensity.
Main innovation point is that large core fiber is used when signal is optically coupled into optical fiber, improves the coupling effect of signal light
Rate.Again by this patent design device, the signal in the optical fiber of big core diameter is optically coupled into the optical fiber of small core diameter, then
The optical fiber of small core diameter is connect with fiber spectrometer, and under the conditions of same slit, then the optical fiber of small core diameter has the signal of greater proportion
It is optically coupled into fiber spectrometer.
The signal strength of spectrum is improved, the time of integration is shortened, accelerates detection speed.
By the fiber coupling after 4 arrays of optical fiber of 105um with 200um, then the fused fiber splice of 4 105um is arrived
The optical fiber of a piece 105um, then by the fused fiber splice after the optical fiber beam expansion of 50um with 105um.

In contradiction, all should be considered as described in this specification.
The embodiments described above only express several embodiments of the present invention, and the description thereof is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that coming for those of ordinary skill in the art
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to protection of the invention
Range.Therefore, the scope of protection of the patent of the invention shall be subject to the appended claims.
