    2. Subsurface and Layer Intertwined Template Protection Using Inherent Properties of Full-Field Optical Coherence Tomography Fingerprint Imaging

      Subsurface and Layer Intertwined Template Protection Using Inherent Properties of Full-Field Optical Coherence Tomography Fingerprint Imaging
      The emergence of Full Field-Optical Coherence Tomography (FF-OCT) for fingerprint imaging has shown its ability in addressing and solving the drawbacks of traditional fingerprinting solutions such as spoofing attacks, low accuracy for abraded fingerprint. With the availability of multiple internal fingerprints (from subsurface captured at different depths), it is also essential to consider the aspects of ideal biometrics where the privacy of the fingerprint data is preserved. In this work ...

    3. In vivo volumetric imaging by crosstalk-free full-field OCT

      In vivo volumetric imaging by crosstalk-free full-field OCT
      Cellular resolution imaging of biological structures has always been a challenge due to strong scattering that limits the achievable transverse resolution or imaging penetration depth. Recently, a major advancement toward high-resolution and volumetric imaging was achieved by implementing a parallel detection (i.e., full field) into Fourier-domain optical coherence tomography. The drawback of using parallel detection is that scattered light can travel laterally and get mapped improperly at a camera ...

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

      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 ...

    5. 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 ...

    6. Full-field optical coherence microscopy is a novel technique for imaging enteric ganglia in the gastrointestinal tract

      Full-field optical coherence microscopy is a novel technique for imaging enteric ganglia in the gastrointestinal tract
      Background Noninvasive methods are needed to improve the diagnosis of enteric neuropathies. Full-field optical coherence microscopy (FFOCM) is a novel optical microscopy modality that can acquire 1 m resolution images of tissue. The objective of this research was to demonstrate FFOCM imaging for the characterization of the enteric nervous system (ENS). Methods Normal mice and EdnrB -/- mice, a model of Hirschsprungs disease (HD), were imaged in three-dimensions ex vivo using ...

  2. About Egidijus Auksorius

    Egidijus Auksorius

    Egidijus Auksorius specializes in the development of optical imaging technologies and its applications. Currently, I am working at the Polish Academy of Sciences on developing fast 3-D imaging technologies. I have recently developed a novel fingerprint sensor at Institut Langevin in Paris that is able to image fingerprints from the inside of a finger. Previous to that, I was working in Prof. Gary Tearney's lab at Harvard Medical School on developing high-resolution bioimaging systems. I received my PhD in Physics from Imperial College London for my work on STED microscopy and Fluorescence Lifetime Imaging (FLIM) in Prof. Paul French's lab, which led to the first demonstration of time-resolved STED microscopy.
