    1. Inspection of Intraocular Lens with Dual-side View Optical Coherence Tomography

      Inspection of Intraocular Lens with Dual-side View Optical Coherence Tomography
      Intraocular lens (IOL) is widely used for cataract treatment. Its optical properties are crucial to obtain a good treatment efficacy and thus need to be evaluated and controlled. In this study, we propose a novel method based on optical coherence tomography (OCT) for noncontact and accurate in vitro measurement of thickness, refractive index and dioptric power of IOL implants. The OCT setup is specially designed to create two sampling optics ...

    2. Dual-side view optical coherence tomography for thickness measurement on opaque materials

      Dual-side view optical coherence tomography for thickness measurement on opaque materials
      Optical coherence tomography (OCT), as an optical interferometric imaging technique, has found wide applications in various fields. In principle, OCT is well suited for imaging layered structures, and thus, one of the typical applications is thickness measurement. However, due to the limited imaging depth resulting from light attenuation, thickness measurement by OCT is limited to non-opaque materials. In this study, we developed a novel (to the best of our knowledge ...

    3. Nondestructive Measurement of Conformal Coating Thickness on Printed Circuit Board with Ultra-high Resolution Optical Coherence Tomography

      Nondestructive Measurement of Conformal Coating Thickness on Printed Circuit Board with Ultra-high Resolution Optical Coherence Tomography
      Conformal coating (CC) is widely used to protect printed circuit board (PCB) from corrosion, mould growth and electrical failures. To ensure an effective protection, the thickness of the conformal coating layer needs to be well controlled. However, to date, the coating thickness is usually measured in a destructive way under microscopes. In this study, we proposed to use optical coherence tomography (OCT) to measure the CC thickness nondestructively. Specifically, to ...

    4. Imaging cellular structures of atherosclerotic coronary arteries using circumferentially scanning micro-optical coherence tomography fiber probe ex vivo

      Imaging cellular structures of atherosclerotic coronary arteries using circumferentially scanning micro-optical coherence tomography fiber probe ex vivo
      Development and progression of coronary atherosclerotic lesions is mediated by a number of cellular components, which are not readily visualized using the current clinical investigation tools. Visualizing these cellular components in situ and in vivo may allow early detection of the vulnerable plaques, with implications for coronary artery disease (CAD) therapy and for the prevention of acute myocardial infarction (AMI). In this study, we have developed a fiber-optic micro-optical coherence ...

    5. Extending axial focus of optical coherence tomography using parallel multiple aperture synthesis

      Extending axial focus of optical coherence tomography using parallel multiple aperture synthesis
      Compromising the inherent trade-off between transverse resolution and depth of focus (DOF) remains a long-standing issue in optical coherence tomography (OCT). In this work, we report a novel techniqueparallel multiple aperture synthesis (pMAS) to simultaneously generate multiple optical apertures in an OCT sample arm by employing a two-surface coated mirror. In the proposed pMAS, the DOF is extended by a factor of 16.49 without sacrificing the transverse resolution for ...

    6. High Resolution Optical Coherence Tomography for Bio-Imaging

      High Resolution Optical Coherence Tomography for Bio-Imaging
      Optical coherence tomography (OCT) is a low-coherence interferometry based bio-imaging technology. It has attracted extensive research interests in recent years for its non-invasive, high-speed and high-resolution properties. Numerous schemes for improving OCT resolutions have been demonstrated in literature. This chapter gives a comprehensive review of the recent developments of spectral domain (SD)-OCT systems with either high axial-resolution or lateral resolution, and then highlights the wide applications of such high-resolution ...
