The different currency types of country or the bank note of different denominations, such as dollar of the RMB of 100 yuan of face amounts, 10 yuan of face amounts etc.,
The embodiment of the present invention is equally not limited this.Illumination pattern can be that phosphor pattern, infrared image and other light sources shine
Penetrate the corresponding pattern or image generated after bank note.
In an alternate embodiment of the present invention where, first conditions of exposure includes：First exposure time and first exposes
The product of luminous intensity is in the first preset range.
Wherein, exposure time refers to the duration that light source irradiates bank note to be detected, and exposure intensity refers to that light source is treated
Detect the light intensity of bank note irradiation.Correspondingly, the first preset range needs to set according to actual demand.
In embodiments of the present invention, bank note to be detected can form different illumination patterns under the irradiation of different light sources.It lifts
For example, as shown in Figure 1 b, the front of the RMB of 100 yuan of face amounts is under the irradiation of ultraviolet source, and 100 in dotted line frame
Fluorescent effect can occur for number, and form corresponding phosphor pattern.It should be noted that Fig. 1 b only schematically illustrate 100

Phosphor pattern and face amount of the reverse side under the irradiation of ultraviolet source, there is no the other informations of the RMB to 100 yuan of face amounts
It is shown.For the positive phosphor pattern of the RMB of 100 yuan of face amounts, in the corresponding ultraviolet light of equal conditions of exposure
Under the irradiation in source, the phosphor pattern distributed areas bigger of reverse side, brightness are relatively weak, and specific pattern also differs.If
Identical conditions of exposure is used to the obverse and reverse of the RMB to be detected of 100 yuan of face amounts, when the conditions of exposure meets front
During the exposure demand of phosphor pattern, the brightness of the phosphor pattern of reverse side can be than relatively low, the ash of part reverse side phosphor pattern at this time
Angle value is approached with background patterns, so as to cause be not easy extract reverse side phosphor pattern data the problem of.When the conditions of exposure is expired
