    3. Nanosensitive optical coherence tomography to assess wound healing within the cornea

      Nanosensitive optical coherence tomography to assess wound healing within the cornea
      Optical Coherence Tomography (OCT) is a non-invasive depth resolved optical imaging modality, that enables high resolution, cross-sectional imaging in biological tissues and materials at clinically relevant depths. Though OCT offers high resolution imaging, the best ultra-high-resolution OCT systems are limited to imaging structural changes with a resolution of one micron on a single B-scan within very limited depth. Nanosensitive OCT (nsOCT) is a recently developed technique that is capable of ...

    4. Feasibility of correlation mapping optical coherence tomography angiographic technique using a 200  kHz vertical-cavity surface-emitting laser source for in vivo microcirculation imaging applications

      Feasibility of correlation mapping optical coherence tomography angiographic technique using a 200  kHz vertical-cavity surface-emitting laser source for in vivo microcirculation imaging applications
      Optical coherence tomography (OCT) angiography is a well-established in vivo imaging technique to assess the overall vascular morphology of tissues and is an emerging field of research for the assessment of blood flow dynamics and functional parameters such as oxygen saturation. In this study, we present a modified scanning-based correlation mapping OCT using a 200 kHz high-speed swept-source OCT system operating at 1300 nm and demonstrate its wide field-imaging capability ...

    5. Characterization of an amplified piezoelectric actuator for multiple-reference optical coherence tomography

      Characterization of an amplified piezoelectric actuator for multiple-reference optical coherence tomography
      The characterization of an amplified piezoelectric actuator (APA) as a new axial scanning method for multiple-reference optical coherence tomography (MR-OCT) is described. MR-OCT is a compact optical imaging device based on a recirculating reference-arm-scanning optical delay using a partial mirror that can enhance the imaging depth range by more than 10 times the reference mirrors scanning amplitude. The scanning amplitude of the used APA was varied between 30 m and ...

      Nano-sensitive fourier-domain optical coherence tomography inspection system
      An OCT imaging system (100) comprising a radiation emitter (SLD), a radiation receiver CCD), an interferometer (FC, PC, X-Scan, Y-Scan), a controller (COMP) which controls the emitter and processes received radiation data according to OCT to provide an output image. The controller (COMP) forms a spectrum of spatial frequencies along the depth direction. It calculates from the spectrum local spectra of spatial frequencies or periods along the depth direction for ...

      Feasibility study of phase-sensitive imaging based on multiple reference optical coherence tomography
      Multiple reference optical coherence tomography (MR-OCT) is a recently developed, low-cost and compact time-domain OCT solution for primary care and consumer level applications. A combination of a voice coil actuator and a partial mirror (PM) extends the scan range for imaging depths of approximately 1 mm in biological samples. Our previous research on MR-OCT is based only on intensity information obtained from the depth-resolved interference signal. In this Letter, we ...

    13. Simultaneous en-face imaging of multiple layers with multiple reference optical coherence tomography

      Simultaneous en-face imaging of multiple layers with multiple reference optical coherence tomography
      A technique based on multiple reference optical coherence tomography (MR-OCT) is proposed for simultaneous imaging at multiple depths. The technique has been validated by imaging a reference sample and a fingerprint in-vivo. The principle of scanning multiple selected layers is shown by imaging a partial fingerprint with 200200200 voxels of 330.5mm size and obtaining an arbitrary amount of layers merely by digital processing. The spacing among the layers can ...

    14. Comparing an FFT filter for multiple reference optical coherence tomography (MR-OCT) with an Chebychev and an elliptic filter

      Comparing an FFT filter for multiple reference optical coherence tomography (MR-OCT) with an Chebychev and an elliptic filter
      Portable and low-cost optical coherence tomography (OCT) is increasingly used to improve the accuracy of point-of-care applications. The increasing research efforts to use photonics integrated circuits (PIC) is without doubts the future for highest packaging densities in miniature optical systems. MR-OCT is another technology that is using the advantages of well known CD/DVD-ROM technology to build miniaturized and low-cost OCT systems and may be more readily available before PICs ...

      Development of a first-generation miniature multiple reference optical coherence tomography imaging device
      Multiple reference optical coherence tomography (MR-OCT) is a technology ideally suited to low-cost, compact OCT imaging. This modality is an extension of time-domain OCT with the addition of a partial mirror in front of the reference mirror. This enables extended, simultaneous depth scanning with the relatively short scan range of a miniature voice coil motor on which the scanning mirror is mounted. This work details early stage development of the ...
