Abstract
A fingerprint collecting device comprises an optical fiber imaging board, an optical imaging lens, an imaging sensor, and an imaging light source, wherein the optical fiber imaging board is positioned in an angle with the optical imaging lens and is equipped with a refractor between them. The utility model does not impact accuracy, compatibility and articulation of the fingerprint image when minimizes the thickness of the collecting device, and resolves the art questions of assembling inconvenience and using with the thick size of the collecting device.
Description
Affiliated technical field
The utility model relates to a kind of fingerprint acquisition device, particularly relates to a kind of imaging fiber plate imaging of passing through, and after the optical imagery camera lens dwindles, is gathered the fingerprint acquisition device of fingerprint by imageing sensor.
Background technology
In the prior art, by the imaging fiber plate, the technical scheme by imageing sensor is gathered fingerprint image is widely used on the various fingerprint collecting input medias.The inventor is " a kind of fingerprint acquisition device " patent of invention of 200510012675.9 the number of applying for a patent on July 11 in 2005, its fingerprint image acquisition technical scheme one is with the imaging fiber plate, optical imagery camera lens and imageing sensor are provided with in line, the imaging on the imaging fiber plate of tested fingerprint, the optical signal image that forms is after the optical imagery camera lens dwindles, and the shot images sensor changes electric signal into, by gathering electric signal, can obtain fingerprint image.The shortcoming of this structure is that imaging fiber plate, optical imagery camera lens and imageing sensor are provided with in line, cause the fingerprint acquisition device enlarged in thickness, make troubles for installation, use.
Summary of the invention
The purpose of this utility model provide a kind of assurance print image accurately, fingerprint image high conformity and fingerprint image simultaneously clearly, effectively reduce the fingerprint acquisition device of harvester thickness.
The technical scheme that its technical matters that solves the utility model adopts is: imaging fiber plate and the angled setting of optical imagery camera lens are provided with the catoptron that the image that can make the imaging fiber plate reflexes to the optical imagery camera lens between imaging fiber plate and the optical imagery camera lens.Catoptron is plane mirror or prism.
The beneficial effects of the utility model are: imaging fiber plate and the angled placement of optical imagery camera lens, effectively reduce fingerprint acquisition device thickness, and be beneficial to installation, use.
Description of drawings

Accompanying drawing 2 is the utility model embodiment 2 structural representations.
Accompanying drawing 3 is the utility model embodiment logic working figure.
1 imaging fiber plate, 2 optical imagery camera lenses, 3 imageing sensors, 4 imaging sources, 5 light reflecting mirrors, 6 tested fingerprints, 7 signal processors in the accompanying drawing
Embodiment
Referring to accompanying drawing 1 the utility model embodiment, 1 structural representation and accompanying drawing 3 the utility model embodiment logic working figure, for guarantee print image accurately, fingerprint image high conformity and fingerprint image simultaneously clearly, effectively reduce the thickness of harvester, imaging fiber plate 1 and the 2 angled placements of optical imagery camera lens are provided with catoptron 5 between imaging fiber plate 1 and the optical imagery camera lens 2.During work, the light that imaging source 4 sends is through imaging fiber plate 1, evenly be transmitted to the surface of tested fingerprint 6, the imaging on imaging fiber plate 1 of tested fingerprint 6, the optical signal image that tested fingerprint 6 forms enters into optical imagery camera lens 2 by catoptron 5, after having optical imagery camera lens 2 to dwindle, shot images sensor 3, change electric signal into, and be input to signal processor 7, handle through signal processing chip 7.
Adopt imaging fiber plate 1 and the 2 angled settings of optical imagery camera lens, effectively reduce fingerprint acquisition device thickness, be beneficial to installation, use, do not influence the accuracy of fingerprint image, the consistance of fingerprint image and the sharpness of fingerprint image simultaneously.
The purpose that catoptron 5 is set is, the optical signal image that tested fingerprint 6 is formed enters into optical imagery camera lens 2 by catoptron 5, make optical imagery camera lens 2 and the 1 angled setting of imaging fiber plate, angle specifically is set can be determined according to the gauge of product requirement, if being set, catoptron 5 of angle can not realize total reflection, can a plurality of catoptrons be set at correspondence position, by a plurality of catoptron continuous reflection, the final realization enters into optical imagery camera lens 2 with the optical signal image that tested fingerprint 6 forms by catoptron 5.
Accompanying drawing 2 is the utility model embodiment 2 structural representations, and catoptron 5 is prism.Prism can make the fingerprint image that is refracted adjust.
Claims (2)
1 one kinds of fingerprint acquisition devices, comprise imaging fiber plate (1), optical imagery camera lens (2), imageing sensor (3) and imaging source (4), it is characterized in that: described imaging fiber plate (1) and the angled setting of optical imagery camera lens (2) are provided with the catoptron (5) that the image that can make imaging fiber plate (1) reflexes to optical imagery camera lens (2) between imaging fiber plate (1) and the optical imagery camera lens (2).
2 a kind of fingerprint acquisition devices according to claim 1 is characterized in that: described catoptron (5) is plane mirror or prism.
