    1. Feasibility of correlation mapping optical coherence tomography (cmOCT) for anti-spoof sub-surface fingerprinting

      Feasibility of correlation mapping optical coherence tomography (cmOCT) for anti-spoof sub-surface fingerprinting

      We propose the use of correlation mapping optical coherence tomography (cmOCT) to deliver additional biometrics associated with the finger that could complement existing fingerprint technology for law enforcement applications. The current study extends the existing fingerprint paradigm by measuring additional biometrics associated with sub-surface finger tissue such as sub-surface fingerprints, sweat glands, and the pattern of the capillary bed to yield a user-friendly cost effective and anti-spoof multi-mode biometric solution associated with the finger. To our knowledge no other method has been able to capture sub-surface fingerprint, papillary pattern and horizontal vessel pattern in a single scan or to show ...

    2. Biophotonics and Imaging Graduate Summer School June 6th - June 12, 2012, Galway Ireland

      Biophotonics and Imaging Graduate Summer School June 6th - June 12, 2012, Galway Ireland

      The international Biophotonics and Imaging Graduate Summer School (BIGSS) is a 5 ECTS credit course run every two years in partnership with Photonics 4 Life and SPIE as an intimate gathering located in the rugged landscape of west coast of Ireland. The peripheral location and limited student numbers are specifically chosen to foster student-tutor interaction and enhance the learning experience. Each school offers an excellent group of international experts giving 4hr lecture series in their specialist areas. There is a focus on quantitative imaging in diagnosis and therapy this year which I think is also very topical.

    3. In-vivo dynamic characterization of microneedle skin penetration using optical coherence tomography

      In-vivo dynamic characterization of microneedle skin penetration using optical coherence tomography
      The use of microneedles as a method of circumventing the barrier properties of the stratum corneum is receiving much attention. Although skin disruption technologies and subsequent transdermal diffusion rates are being extensively studied, no accurate data on depth and closure kinetics of microneedle-induced skin pores are available, primarily due to the cumbersome techniques currently required for skin analysis. We report on the first use of optical coherence tomography technology to image microneedle penetration in real time and in vivo. We show that optical coherence tomography (OCT) can be used to painlessly measure stratum corneum and epidermis thickness, as well as ...

    4. A gel-based skin and blood flow model for a Doppler optical coherence tomography (DOCT) imaging system

      A gel-based skin and blood flow model for a Doppler optical coherence tomography (DOCT) imaging system
      Since its discovery in 1842 by Christian Johann Doppler, the Doppler Effect has had many applications in the scientific world. In recent years, the phenomenon has been integrated with Optical Coherence Tomography (OCT) yielding Doppler Optical Coherence Tomography (DOCT), a technique that is useful for high-resolution imaging of the skin microcirculation. However, interpretation of DOCT images is rather challenging. Thus, our study aims to aid understanding of DOCT images with respect to parameters of microcirculation components such as blood vessel size, depth and angular position. To this end, we have constructed a gel-based tissue and blood-flow model for performing DOCT ...
