    2. Multispectral photoacoustic microscopy and optical coherence tomography using a single supercontinuum source

      Multispectral photoacoustic microscopy and optical coherence tomography using a single supercontinuum source
      We report on the use of a single supercontinuum (SC) source for multimodal imaging. The 2-octave bandwidth (4752300 nm) makes the SC source suitable for optical coherence tomography (OCT) as well as for multispectral photoacoustic microscopy (MPAM). The IR band centered at 1310 nm is chosen for OCT to penetrate deeper into tissue with 8 mW average power on the sample. The 500840 nm band is used for MPAM. The ...

    3. Q-switched based supercontinuum source towards low-cost ultra-high resolution optical coherence tomography

      Q-switched based supercontinuum source towards low-cost ultra-high resolution optical coherence tomography
      Supercontinuum (SC) light source is certainly one of the best option for ultra-high resolution optical coherence tomography (UHR-OCT). Over the last few years several demonstrations have been done for each commonly used wavelength range [1-2-3]. Nowadays, SC dedicated to UHR-OCT is a mature technology with turn-key commercially available system [4]. The new challenge to answer for SC source is the cost reduction one. In this study, we demonstrate that a ...

    4. Two optical coherence tomography systems detect topical gold nanoshells in hair follicles, sweat ducts and measure epidermis

      Two optical coherence tomography systems detect topical gold nanoshells in hair follicles, sweat ducts and measure epidermis
      Optical coherence tomography (OCT) is an optical imaging technology that enables real time, high‐resolution, cross‐sectional and en face investigation of skin by detecting reflected broad‐spectrum near‐infrared light from tissue. OCT provides micron‐scale spatial resolution and millimeter‐scale depth of penetration [1]. Several commercial OCT systems with handheld probes targeted for Dermatology are now available [2].

    5. In-vivo detection of the skin dermo-epidermal junction by ultrahigh resolution optical coherence tomography

      In-vivo detection of the skin dermo-epidermal junction by ultrahigh resolution optical coherence tomography
      The human skin is comprised by two layers; epidermis and dermis, separated by the dermo-epidermal junction (DEJ). The relevance of depicting DEJ and measurement of the epidermal thickness (ET) is e.g. seen for superficial skin cancers where delineation of DEJ is of prime prognostic importance. Another example is diagnosis of psoriasis where a thickened epidermis and a ridged DEJ is a hallmark. Histopathological examination of biopsied tissue is traditionally ...

    6. Q-switch-pumped supercontinuum for ultra-high resolution optical coherence tomography

      Q-switch-pumped supercontinuum for ultra-high resolution optical coherence tomography
      In this Letter, we investigate the possibility of using a commercially availableQ-switch-pumped supercontinuum (QS-SC) source, operating in the kilohertz regime, for ultra-high resolution optical coherence tomography (UHR-OCT) in the 1300nm region. The QS-SC source proves to be more intrinsically stable from pulse to pulse than a mode-locked-based SC (ML-SC) source while, at the same time, is less expensive. However, its pumping rate is lower than that used in ML-SC sources ...

    8. A comparative study of noise in supercontinuum light sources for ultra-high resolution optical coherence tomography at 1300 nm

      A comparative study of noise in supercontinuum light sources for ultra-high resolution optical coherence tomography at 1300 nm
      Supercontinuum (SC) light is a well-established technology, which finds applications in several domains ranging from chemistry to material science and imaging systems [1-2]. More specifically, its ultra-wide optical bandwidth and high average power make it an ideal tool for Optical Coherence Tomography (OCT). Over the last 5 years, numerous examples have demonstrated its high potential [3-4] in this context. However, SC light sources present pulse-to-pulse intensity variation that can limit ...

      Supercontinuum light source, a system and a method of measuring
      A supercontinuum light source comprising an intermediate supercontinuum light source and a single mode coupling unit, an optical measurement system comprising such light source, as well as a method of measuring are described. The supercontinuum light source comprises a pulse frequency multiplier to increase the repetition rate and the single mode coupling unit is arranged to dampen and shape the spectrum from the intermediate supercontinuum light source to allow measurements ...

    10. Acousto-optic tunable filter for dispersion characterization of time-domain optical coherence tomography systems

      Acousto-optic tunable filter for dispersion characterization of time-domain optical coherence tomography systems
      A broadband supercontinuum light source with an acousto-optic tunable filter (AOTF) are used to characterize dispersion in two time-domain OCT systems, at 850 and 1300 nm. The filter is designed to sweep across two spectral ranges, which are restricted here from 800 to 900 nm and from 1200 to 1500 nm, respectively. Dispersion compensation for 850 nm was achieved with a spectral delay line. Dispersion compensation for 1300 nm was ...

      Beyond Better Clinical Care: Optical Coherence Tomography's Economic Impact
      The optical coherence tomography (OCT) industry has grown dramatically in its first 25 years, and while the positive effects on patient clinical care are the most important measure of OCT's success, its contributions to the economy in jobs, tax receipts, and healthcare savings are also noteworthy. The field of optical coherence tomography (OCT) has grown dramatically since its discovery in the early 1990s. The commercialization and growth of OCT ...

      Feature of the Week 05/08/2016: Complex Master Slave Interferometry
      A general theoretical model is developed to improve the novel Spectral Domain Interferometry method denoted as Master/Slave (MS) Interferometry. In this model, two functions, g and h are introduced to describe the modulation chirp of the channeled spectrum signal due to nonlinearities in the decoding process from wavenumber to time and due to dispersion in the interferometer. The utilization of these two functions brings two major improvements to previous ...
