      Introduction to the feature issue on the 25 year anniversary of optical coherence tomography
      This feature issue commemorates the approximately 25 year history of Optical Coherence Tomography (OCT), one of the most successful biophotonic technologies. While OCT has technological origins traceable to ultrafast laser development and fiber optic system test instrumentation of the 1980s, innovations in low coherence interferometry for optical ranging and imaging for biomedical applications in the U.S., Europe and Japan by the early 1990s led to coinage of the now ...

      Intravascular optical coherence tomography [Invited]
      Shortly after the first demonstration of optical coherence tomography for imaging the microstructure of the human eye, work began on developing systems and catheters suitable for intravascular imaging in order to diagnose and investigate atherosclerosis and potentially to monitor therapy. This review covers the driving considerations of the clinical application and its constraints, the major engineering milestones that enabled the current, high-performance commercial imaging systems, the key studies that laid ...

      Endoscopic optical coherence tomography: technologies and clinical applications [Invited]
      In this paper, we review the current state of technology development and clinical applications of endoscopic optical coherence tomography (OCT). Key design and engineering considerations are discussed for most OCT endoscopes, including side-viewing and forward-viewing probes, along with different scanning mechanisms (proximal-scanning versus distal-scanning). Multi-modal endoscopes that integrate OCT with other imaging modalities are also discussed. The review of clinical applications of endoscopic OCT focuses heavily on diagnosis of diseases ...

      Laser speckle microrheometer for measuring mechanical properties of biological tissue
      Volumetric distribution of a micromechanical parameter of a biological tissue, such as viscoelastic parameter or tissue stiffness, is determined, with microscopic resolution, from optical data representing light scattered by sequential layers of the tissue and, optionally, displayed to visualization. A particular layer of the tissue is defined through coherence-gating of light received at the optical detector. Coherence-gating is achieved with the use of an interferometer the sample arm of which ...

      Illuminating dynamic neutrophil trans-epithelial migration with micro-optical coherence tomography
      A model of neutrophil migration across epithelia is desirable to interrogate the underlying mechanisms of neutrophilic breach of mucosal barriers. A co-culture system consisting of a polarized mucosal epithelium and human neutrophils can provide a versatile model of trans-epithelial migration in vitro , but observations are typically limited to quantification of migrated neutrophils by myeloperoxidase correlation, a destructive assay that precludes direct longitudinal study. Our laboratory has recently developed a new ...

      Extended bandwidth wavelength swept laser source for high resolution optical frequency domain imaging
      Improving the axial resolution by providing wider bandwidth wavelength swept lasers remains an important issue for optical frequency domain imaging (OFDI). Here, we demonstrate a wide tuning range, all-fiber wavelength swept laser at a center wavelength of 1250 nm by combining two ring cavities that share a single Fabry-Perot tunable filter. The two cavities contain semiconductor optical amplifiers with central wavelengths of 1190 nm and 1292 nm, respectively. To avoid ...

      Assessment of ciliary phenotype in primary ciliary dyskinesia by micro-optical coherence tomography
      Ciliary motion defects cause defective mucociliary transport (MCT) in primary ciliary dyskinesia (PCD). Current diagnostic tests do not assess how MCT is affected by perturbation of ciliary motion. In this study, we sought to use micro-optical coherence tomography (OCT) to delineate the mechanistic basis of cilia motion defects of PCD genes by functional categorization of cilia motion. Tracheae from three PCD mouse models were analyzed using OCT to characterize ciliary ...
