In the specific implementation, as shown in figure 3, molecule sensor 300 can include light source 301 and receiver 302.
Wherein, light source 301 can launch near infrared light, generally, the EWL of near infrared light can be 720nm~
1070nm, for example, light source 301 can be LED (Light-Emitting Diode, light emitting diode) transmitting tube.
Receiver 302 can be the light sensor for receiving sample reflected light, and generally, the sensitivity of receiver 302 is small
In 10nm, for example, 8nm.
In an example of the embodiment of the present invention, receiver is provided with multistage dispersion means.
As shown in figure 4, receiver is internally provided with slit 421, using reflective mirror 422 as the dispersion means of the first order, with
Dispersion means of the grating 423 as the second level, using reflective mirror 424 as the dispersion means of the third level, the light 410 of transmitting is injected narrow

Embodiment is not also any limitation as to this.
At present, bank note is typically to be printed with print paper money paper (banknote paper), prints paper money paper category dedicated paper, can be used for
It is false proof, control typically by special permission manufacturer production and strictly, be difficult to circulate on the market.
Print paper money paper main raw material(s) is cotton fiber and the wood pulp of high quality, and it is peculiar that some countries add this country also in paper pulp
Product or chemical element, for example, printing yen print paper money paper in three fork skin compositions, printing French Franc print paper money paper A Liehe
River, etc..It is of course also possible to add some artificial special marking things prepared or synthesized.
The composition for printing paper money paper is usually unique so that the composition of bank note is also unique, for example, the print of printing RMB
Paper money paper is that 70% or so cotton fiber is mixed made of other special wood-fibreds, therefore, can be based on bank note papery (such as print paper money
Paper) composition to bank note carry out true or false checking.
In bank note, especially fringe region has papery region, that is, appears the region of print paper money paper, no metal wire, ink
Etc. blocking.
Need to be explanation, papery region can be set by those skilled in the art according to actual conditions, different
Country, different denominations, the bank note of different editions, its papery region may be different, and the embodiment of the present invention is not limited this
System.
For example, as shown in fig. 6, at the RMB back side of the 5th set of 100 yuan of face amounts, region 601, region 602, region 603,
Region 604 could be arranged to papery region.
In embodiments of the present invention, user can be with hand-held mobile terminal, by molecule sensor in face of bank note to be verified
Papery region, control molecule sensor launch the near infrared light of one section of wavelength to papery region, the molecule absorption in papery region

Step 103, papery infrared spectrogram is drawn using the papery characteristic light.
When the infrared light of certain frequency passes through molecule, absorbed by the key of identical vibration frequency in molecule, record gained passes through
The curve of rate is referred to as infrared spectrogram.
In a kind of representation of infrared spectrogram, abscissa is wavelength X (μm) and/or the λ (cm of wave number 1/-1), indulge and sit
It is designated as trap A.
In another representation of infrared spectrogram, abscissa is wavelength X (μm) and/or the λ (cm of wave number 1/-1), indulge
Coordinate is percentage transmitance T% (i.e. percentage of the light through sample).
Molecule sensor is faced into a certain electromagnetic radiation near infrared light, and receives the light of its reflection, utilizes the light of transmitting
Infrared spectrogram can be drawn.
For example, as shown in fig. 7, molecule sensor is launched near infrared light in face of desktop, there is different compositions in desk,
Such as wood, paint, different molecular links can be reacted the near infrared light of different wave length accordingly, so as to utilize reflection
Light draw out infrared spectrogram.
In embodiments of the present invention, the papery characteristic light of papery region reflection can be used, draws infrared spectrogram, is obtained
Papery infrared spectrogram.
Step 104, the papery composition of the bank note is identified using the papery infrared spectrogram.
By papery infrared spectrogram measure different wave length near infrared light reflect after attenuation degree, can be with body
Reveal the characteristic of bank note papery (such as print paper money paper) composition, determine whether the bank note papery is print paper money paper, so as to judge bank note
True or false.
In embodiments of the present invention, in the specific implementation, papery infrared spectrogram can be referred into infrared light with default
Spectrogram is matched.
When the match is successful, extraction refers to composition corresponding to infrared spectrogram, the papery composition as bank note.
One way in which, spectrum chart database can be established in server, be stored in the spectrum chart database big
The infrared spectrogram of sample is measured, the sample can record composition, for example, phosphorus content 50%, oxygen content 30%, etc..
Mobile terminal can upload onto the server papery infrared spectrogram, and server can be with the infrared spectrum of its storage
Figure, which is used as, refers to infrared spectrogram, and calculates similarity with papery infrared spectrogram, if similarity is higher than threshold set in advance
Value, then it is considered that both the match is successful, otherwise it is assumed that both it fails to match.
It is speed to accelerate matching, corresponding to the sample that bank note related specy (such as paper, fabric etc.) can be retrieved
Infrared spectrogram, as with reference to infrared spectrogram.
Certainly, Cellular spectroscopic picture library can also be locally stored in mobile terminal, and red by what is stored in Cellular spectroscopic picture library
External spectrum figure is used as and refers to infrared spectrogram, and is matched with papery infrared spectrogram, and the embodiment of the present invention is not subject to this
Limitation.
Step 105, the papery composition is matched with the target papery composition of genuine article coin, obtains matching result.
In the specific implementation, the target papery composition of one or more genuine article coin can be asked to server, with papery into
Divide and matched.
Because the papery composition of genuine article coin is because having fluctuation, therefore, its target papery composition could be arranged to a model
Enclose, if papery composition falls into the scope, it is considered that both matchings, conversely, both mismatch.
Step 106, according to the matching result, the true and false of the bank note is determined.
In oneainstance, when the success of the target papery mating chemical composition of papery composition and genuine article coin, it is true to determine bank note
Currency.
In another scenario, when the target papery mating chemical composition of papery composition and genuine article coin fails, determine that bank note is
False money.
If the match is successful for both, then it represents that currency to be detected has identical papery composition with genuine article coin, it is believed that
Currency to be detected is genuine article coin, i.e. genuine notes.
If the match is successful for both, then it represents that currency to be detected has different papery compositions from genuine article coin, it is believed that
Currency to be detected is fake products coin, i.e. counterfeit money.
So, in the embodiment of the present invention, by configuring molecule sensor in the terminal, molecule sensor is to bank note
Papery field emission near infrared light and the papery characteristic light for receiving its reflection, papery infrared spectrogram are drawn to it, to identify it
Papery composition, and matched in the target papery composition of genuine article coin, verify the true or false of bank note, due to the papery composition of bank note
Usually unique, and be strictly controlled, it is difficult to circulate on the market, therefore, criminal is difficult to the paper for forging printing of currency papers
So that the papery composition between genuine article coin and fake products coin has larger difference, can detect bank note paper by molecule sensor
The molecular characterization of matter, so as to verify the true or false of the bank note exactly, mobile terminal is easy to carry, and user can easily verify
The true or false of bank note, the true or false of manual authentication bank note is avoided, greatly reduce the circulation of counterfeit money, reduce and user is caused
Loss, slow down may caused by economic problems.
Second embodiment
Reference picture 8, the flow chart of the authenticity verification method of another bank note of one embodiment of the invention is shown, applied
In the terminal, the mobile terminal configuration has molecule sensor, and methods described specifically may include steps of：
Step 801, papery field emission near infrared light of the molecule sensor to bank note is driven.
In one embodiment of the invention, mobile terminal configuration has camera, can call camera, be passed by molecule
When sensor faces bank note to be verified, view data is gathered to bank note.
Detection zone is loaded on the image data, detects papery region in the detection area.
Wherein, there is a test point, the test point can be with indication molecule sensor emission near infrared light in detection zone
Direction.
In oneainstance, molecule sensor is not rotatable, then test point is relatively-stationary, and user can be according to detection
The position movement mobile terminal of point so that test point is fallen into papery region.
In another scenario, molecule sensor can rotate within the specific limits, then test point can be within the specific limits
Rotate, if detecting papery region, mobile terminal can rotate molecule sensor so that test point falls into papery region
In.
When test point is located at papery region, driving molecule sensor launches near infrared light along test point.
For example, as shown in figure 9, user by mobile terminal towards bank note when, drive rearmounted camera collection image data,
Detection zone 901 is loaded on the image data, detects the edge of bank note by edge detection algorithm in detection zone 901, then
The UNICOM region of white is detected in edge, papery region is identified, if test point 902 is located in papery region, towards inspection
Measuring point 902 launches near infrared light so that near infrared light can be mapped to papery region.
Step 802, the papery reflected the near infrared light in the papery region spy is received by the molecule sensor
Levy light.
Step 803, papery infrared spectrogram is drawn using the papery characteristic light.
In one embodiment of the invention, because near infrared light has certain penetrability, and bank note is typically relatively thin, closely
Infrared light may penetrate bank note, other objects of directive, cause the papery characteristic light of reflection to be mingled with the characteristic of other objects.
Therefore, in embodiments of the present invention, bank note can be placed on a support object, and the support object can be to light
The object of line reflection, for example, minute surface etc. has the object of smooth surface.
Mobile terminal can obtain the object features light to support object emission infrared light and reflection.
It should be noted that not placing bank note on support now, i.e., object features light is usually to carry support
The characteristic of body, and the characteristic of bank note papery is not carried.
In a kind of mode, user can face molecule sensor support, control molecule sensor transmitting infrared light
Line and the object features light for receiving its reflection.
In a further mode of operation, some conventional supports can be locally stored in server and/or mobile terminal in advance
The object features light to infrared light reflection of body.
User can select the information (such as species, title) of support object in mobile terminal, in server and/or movement
Terminal local inquires about object features light corresponding to the support object.
Now, in the terminal have on same support object, place bank note when papery characteristic light and do not place
Object features light during bank note.
On the one hand, the first infrared spectrogram is drawn using object features light.
On the other hand, the second infrared spectrogram is drawn using papery characteristic light.
Second infrared spectrogram is subtracted into the first infrared spectrogram, papery infrared spectrogram is obtained, now, after subtracting each other
Spectrum is more pure, can reduce the influence caused by the characteristic for other objects being mingled with papery characteristic light.
Certainly, in addition to spectrum subtracts each other, papery infrared spectrogram, this hair directly can also be drawn using papery characteristic light
Bright embodiment is not any limitation as to this.
Step 804, monetary information corresponding to the bank note is determined.
In the specific implementation, because the print paper money paper that different bank note uses is different, hence, it can be determined that the goods of bank note
Coin information, for example, species (such as RMB, dollar, sterling), version (such as the 5th edition RMB), face amount (such as 100,50,
20th, 10 etc.) etc., so as to distinguish the checking that different bank note carries out true or false.
In oneainstance, user can directly input monetary information.
In another scenario, the number for identifying language, representing face amount can be passed through in the view data gathered to bank note
Word, feature object (such as watermark, head portrait, Background Buildings thing) identification monetary information.
Step 805, Infrared Targets spectrogram is searched.
In embodiments of the present invention, Infrared Targets spectrogram is to genuine article coin corresponding to monetary information using near infrared light
Papery region detect the infrared spectrogram of acquisition.
In a kind of mode, spectrum chart database can be established in server, be stored in the spectrum chart database big
Measure the infrared spectrogram of sample.
In the specific implementation, spectrum chart database can be safeguarded by the whole network user, i.e., the whole network user can use and divide
After sub- sensor detects the infrared spectrogram of some material, the shorthand information (such as title, kind) of the sample is marked, is uploaded
To server, can also be safeguarded by the testing agency of specialty, i.e., professional structure is using equipment or molecules such as infrared spectrometers
After sensor detects the infrared spectrogram of some material, the details (such as water content, sugar content) of the sample are marked, on
Server, etc. is reached, the embodiment of the present invention is not any limitation as to this.
In the manner, monetary information can be sent to server, server and be looked into spectrum chart database by mobile terminal
Infrared spectrogram corresponding to the monetary information is ask, as Infrared Targets spectrogram, and returns to mobile terminal.
In a further mode of operation, Cellular spectroscopic picture library can be established to sample in spectrum chart database, in a cell
The infrared spectrogram of the sample with identical characteristic can be stored in spectrum picture library.
For example, establish a Cellular spectroscopic picture library to the RMB of the 5th edition, to different times (such as the growth stage, the maturity period,
After taking etc.) apple establish a Cellular spectroscopic picture library, a Cellular spectroscopic picture library is established to the human body under different body temperature, etc.
Deng
User can download one or more Cellular spectroscopic picture libraries from server, be stored in mobile terminal sheet as desired
Ground.
For example, if user manages shop, the circulation of bank note is very big, can download what the RMB of the 5th edition was established
Cellular spectroscopic picture library.
In the manner, Cellular spectroscopic picture library corresponding to monetary information can be searched in the terminal, in the cell light
Infrared Targets spectrogram corresponding to the spectrogram library lookup monetary information.
It should be noted that bank note there may be consume in the process of circulation so that slight change occurs in the papery of bank note
Change, therefore, the papery region of the affiliated genuine article coin of monetary information can be directed to, examined under the different environment such as washing, contamination greasy dirt
Corresponding Infrared Targets spectrogram is surveyed, i.e. the quantity of Infrared Targets spectrogram can be one or more.
Step 806, the papery infrared spectrogram is matched with the Infrared Targets spectrogram.
Step 807, when the match is successful, it is genuine article coin to determine the bank note.
Step 808, when it fails to match, it is false money to determine the bank note.
In the specific implementation, papery infrared spectrogram and one or more Infrared Targets spectrograms can be calculated into phase respectively
Like degree.
If similarity is higher than threshold value set in advance, can consider both, the match is successful, otherwise it is assumed that both matchings
Failure.
If the match is successful for both, then it represents that currency to be detected has identical papery composition with genuine article coin, it is believed that
Currency to be detected is genuine article coin, i.e. genuine notes.
If the match is successful for both, then it represents that currency to be detected has different papery compositions from genuine article coin, it is believed that
Currency to be detected is fake products coin, i.e. counterfeit money.
It should be noted that for embodiment of the method, in order to be briefly described, therefore it is all expressed as to a series of action group
