Description
Technical field
The invention belongs to the weak coherence tomography technique of holographic field, more particularly to a kind of using the weak coherent tomographic of holographic field
The method that Imaging carries out identification to imaging biological tissue
Background technology
World's exchange is more and more frequently extensive, while terrified and criminal activity also grows in intensity, thus biological identification technology
In recent years demand growth is rapid, proposes requirements at the higher level to fast and accurately authentication.
Due to conventional fingerprint recognition methods, easily cheated by [IET Biometrics, pp.219 with replicating fingerprint
233 (2014)], and finger surface make dirty, overly wet or abrasion then fail [Handbook of Fingerprint
Recognition, p.496 (2009)], security and robustness are under suspicion, by every country safety and law enforcement agency
Drive, the technology such as face recognition, Application on Voiceprint Recognition, cheilogramma identification, iris structure and retinal vein identification constantly develops, but these
Or technology reliability exist dispute, or use and its inconvenient, bulky, cost too high.
Topping discusses interior fingerprint for the uniqueness and not of bio-identification in patent (US5,751,835,1998)
Reproducibility.In the skin layer of finger interior 220-550 μm, with surface (outside) fingerprint identical topological characteristic [The
fingerprint sourcebook(2011)].These interior layers, serve as the shape that " master module " causes outside fingerprint according to it
Growth, therefore, the not affected by environment and abrasion of subcutaneous fingerprint, it is difficult to imitated, more accurate for identification.In addition, in finger
The sweat gland [IEEE Trans.Pattern Anal.Mach.Intell.29 (1), 15 27 (2007)] in portion and microvessel structure
Shape [.Anat.204 (2), 123 131 (2004)] is followed with fingerprint.We define interior fingerprint for subcutaneous fingerprint, and corresponding
The institutional framework such as the sweat gland of aspect and capillary, it have lifelong consistency [The fingerprint sourcebook
(2011)], can be used for accurately and the identification of the biometric identity of height robust.
In current fingerprint identification technology, the fingerprint extraction such as optics, electric capacity, thermal map, pressure sensitivity mode cannot all obtain interior finger
Line.And ultrasonic method cannot be also applied because detector size is excessive, response speed is slow, processing system is huge.The U.S. stops within 2006
Si Dun university Larin KV [IEEE Photonics Technol.Lett.19 (20), 1,634 1636 (2007)] is proposed with sweeping
Frequency tomography obtains interior fingerprint, but traditional chromatography imaging technique is extracted to two-dimentional direct picture and needs point-to-point scanning, and

Spend slow (more than 10 seconds).In addition, interior lactulum unguis [Expert Syst.Appl.41,2,373-386 (2014)] image is also difficult to
Imitated, the high safety living things feature recognition that can be used for.
The present invention is proposed using becoming inside the internal fingerprint of the weak coherence chromatographic imaging art of holographic field, interior lactulum unguis or iris tissue
As carrying out bio-identification, system has Non-contact nondestructive detectability, can disposably extract biological tissue X-Y scheme with no-raster
Picture, overcomes traditional shortcoming that tomography skill sweep speed is slow, data volume is big；Meanwhile, determine figure using system reference minute surface
As the position of section, can incline or multiple image is used in combination, it might even be possible to the finger print data that compatible conventional method is set up
Storehouse, interior lactulum unguis database, iris database, and pass through while preventing deception, security and robustness are greatly improved.
