      Fast subsurface fingerprint imaging with full-field optical coherence tomography system equipped with a silicon camera

      Images recorded below the surface of a finger can have more details and be of higher quality than conventional surface fingerprint images. This is particularly true when the quality of the surface fingerprints is compromised by, for example, moisture or surface damage. However, there is an unmet need for a cost effective fingerprint sensor that could record high-quality images at sufficient depth below the surface and in short-enough time. To this end, we report on a relatively inexpensive full-field optical coherent tomography (FF-OCT) system comprised of a novel silicon camera and a LED source emitting at 850 nm. The system ...

    2. Fingerprint imaging from the inside of a finger with full-field optical coherence tomography

      Fingerprint imaging from the inside of a finger with full-field optical coherence tomography

      Imaging below fingertip surface might be a useful alternative to the traditional fingerprint sensing since the internal finger features are more reliable than the external ones. One of the most promising subsurface imaging technique is optical coherence tomography (OCT), which, however, has to acquire 3-D data even when a single en face image is required. This makes OCT inherently slow for en face imaging and produce unnecessary large data sets. Here we demonstrate that full-field optical coherence tomography (FF-OCT) can be used to produce en face images of sweat pores and internal fingerprints, which can be used for the identification ...

    3. Dual-modality fluorescence and full-field optical coherence microscopy for biomedical imaging applications

      Dual-modality fluorescence and full-field optical coherence microscopy for biomedical imaging applications

      Full-field optical coherence microscopy (FFOCM) is a high-resolution interferometric technique that is particularly attractive for biomedical imaging. Here we show that combining it with structured illumination fluorescence microscopy on one platform can increase its versatility since it enables co-localized registration of optically sectioned reflectance and fluorescence images. To demonstrate the potential of this dual modality, a fixed and labeled mouse retina was imaged. Results showed that both techniques can provide complementary information and therefore the system could potentially be useful for biomedical imaging applications.
