Visible light in the full spectrum light source in the utility model can white light, it also can be the visible light of single wavelength, it also can be the visible light of multiple different wave length, the light of each wavelength in the full spectrum light source all is provided with independent control electrode, just can carry out independent light emitting control to the light of this wavelength by the pairing control electrode of the light of this wavelength being applied certain voltage.
The reflected image information that the reverberation photographic department obtains when receiving visible or infrared light irradiation original copy, the exciting light image information that the exciting light photographic department obtains when receiving the UV-irradiation original copy.
The utility model scribbles the ultraviolet light filter coating in order to obtain exciting light image information clearly on exciting light photographic department surface.
Reverberation photographic department and exciting light photographic department use common lens unit to receive image information in the utility model.
Reverberation photographic department and exciting light photographic department are outwards exported the original copy information timesharing that receives in the utility model.
Effect of the present utility model is, use a transducer can the reflected light information of original copy be read, also can the exciting light information of original copy be read, improved the function of transducer greatly, thereby make imageing sensor can access better development and application in the anti-counterfeiting detection field.

Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment 1: Fig. 1 is the cross-section structure of the utility model embodiment 1, and Fig. 2 is the internal structure schematic diagram of Fig. 1.1 is the full spectrum light source that can send ultraviolet light, visible light and infrared light among the figure, the 2nd, lens, 3a is the receiver lens 2 reflection of light light photographic department that converges, 3b is the exciting light photographic department of receiver lens 2 light that converges, the 4th, carry the photosensitive integrated circuit 3a be arranged in a straight line and the sensor base plate of 3b, the 6th, hold the framework of light source 1, lens 2, sensor base plate 4,5 are arranged on the light-passing board of the lift-launch original copy on the framework 6, the 8th, be coated in the ultraviolet light filter coating on the 3b, 10 is original copy.
In above-mentioned image read-out, light source 1 is for sending the full spectrum light source of ultraviolet light 204, visible light 200 and infrared light 205, wherein visible light is three primary colors visible light (ruddiness 201, green glow 202, a basket light 203), its structure as shown in Figure 3, wherein 100 is the public electrode of light source, 101 is the ultraviolet light control electrode, 102 is the blue light control electrode, 103 is the green glow control electrode, and 104 is the ruddiness control electrode, and 105 are infrared light control electrode.The light that is each wavelength can carry out independent light emitting control, above-mentioned same as the prior art, this does not give unnecessary details, adding certain voltage by the different lighting electrode to light source 1 just can make light former 1 send the light of different wavelength, these light transmission light-passing boards 5 shine on the original copy 10 of outside.When the visible light in the light source 200 (ruddiness 201, green glow 202 or basket light 203) when being lighted, also the reverberation photographic department is opened simultaneously, the surface reflection of original copy 10 passes lens and enters the reverberation photographic department, and is converted into the signal of telecommunication and outwards transmits; When the infrared light in the light source 205 is lighted, also the reverberation photographic department to be opened simultaneously, the internal reflected light of original copy 10 passes lens and also enters the reverberation photographic department, and is converted into the signal of telecommunication and outwards transmits; When the ultraviolet light in the light source 204 is lighted, at this moment the exciting light photographic department is opened, the exciting light that original copy 10 is produced by ultraviolet light 204 irradiations passes lens and enters into the exciting light photographic department, and be converted into the signal of telecommunication and outwards transmit, Fig. 4 is the schematic diagram of the light of different colours in the light source pairing output signal when being lighted, a kind of light of every unlatching will produce in the output signal 300 and the corresponding photoelectric conversion signal of this light.So, the information of the surface image information of original copy, internal image information and the exciting light that comprised can both use same transducer to read.
Because during ultraviolet light 204 irradiation original copys except producing exciting light, also can produce simultaneously the reverberation of some ultraviolet lights 204, these reverberation also might arrive the exciting light photographic department through lens the exciting light signal is caused interference, so the reverberation of ultraviolet light 204 will be removed.The method that adopts in the present embodiment is to scribble the ultraviolet light filter coating on exciting light photographic department surface, this filter coating can filter ultraviolet light, and do not influence composition is that the exciting light of visible light passes through, No. 2008202390350 patents of the structure of filter coating and processing method and our company are identical, its characteristic as shown in Figure 5, X-axis is a wavelength, Y-axis is a transmitance, use after this filter coating, the exciting light photographic department just can obtain exciting light image information clearly.
Embodiment 2: present embodiment is that its structure section figure as shown in Figure 6 with full spectrum light source separated into two parts structurally.In the present embodiment, light source is made of 1a and 1b.1a is the UV-light luminous part, and 1b is the luminous component of visible light and infrared light, and its operation principle as hereinbefore.
Embodiment 3: be to scribble the ultraviolet light filter coating on exciting light photographic department surface in the foregoing description, also can use kin filter coating or filter on other position of the light path between exciting light photographic department and the original copy reverberation.
