    2. Volumetric rendering and metrology of spherical gradient refractive index lens imaged by angular scan optical coherence tomography system

      Volumetric rendering and metrology of spherical gradient refractive index lens imaged by angular scan optical coherence tomography system
      In this paper, we develop the methodology, including the refraction correction, geometrical thickness correction, coordinate transformation, and layer segmentation algorithms, for 3D rendering and metrology of a layered spherical gradient refractive index (S-GRIN) lens based on the imaging data collected by an angular scan optical coherence tomography (OCT) system. The 3D mapping and rendering enables direct 3D visualization and internal defect inspection of the lens. The metrology provides assessment of ...

    3. MEMS-based handheld scanning probe with pre-shaped input signals for distortion-free images in Gabor-domain optical coherence microscopy

      MEMS-based handheld scanning probe with pre-shaped input signals for distortion-free images in Gabor-domain optical coherence microscopy
      High-speed scanning in optical coherence tomography (OCT) often comes with either compromises in image quality, the requirement for post-processing of the acquired images, or both. We report on distortion-free OCT volumetric imaging with a dual-axis micro-electro-mechanical system (MEMS)-based handheld imaging probe. In the context of an imaging probe with optics located between the 2D MEMS and the sample, we report in this paper on how pre-shaped open-loop input signals ...

    4. Optical Coherence Tomography Enabling Non Destructive Metrology of Layered Polymeric GRIN Material

      Optical Coherence Tomography Enabling Non Destructive Metrology of Layered Polymeric GRIN Material
      Gradient Refractive INdex (GRIN) optical components have historically fallen short of theoretical expectations. A recent breakthrough is the manufacturing of nanolayered spherical GRIN (S-GRIN) polymer optical elements, where the construction method yields refractive index gradients that exceed 0.08. Here we report on the application of optical coherence tomography (OCT), including micron-class axial and lateral resolution advances, as effective, innovative methods for performing nondestructive diagnostic metrology on S-GRIN. We show ...

    5. Liquid lens enabled optical coherence microscope with Gabor fusion

      Liquid lens enabled optical coherence microscope with Gabor fusion
      A custom optical microscope with an integrated liquid lens to enable an extended depth imaging in biological tissue has been fabricated and shown to provide subcellular resolution using Gabor image fusion in an optical coherence tomography setup. In this paper, we report on the development and assessment path of this technology over the last few years. Specifically, we report on the optical design as well as the MTF prediction and ...

  2. About Kevin P. Thompson

    Kevin P. Thompson

    Kevin Thompson is Vice President of Optical Engineering Services at Optical Research Associates.  Dr. Thompson has been promoted to SPIE Fellow. Dr. Thompson's significant contributions to the field include the development of new capabilities in optical design software, particularly for nonsymmetrical optical design, sensitivity analysis methods for one-of-a-kind optical systems, holographic optical design tools, and the enhancement of user environments for improving flexibility for state-of-the-art design problems. Dr. Thompson was the principal optical designer for pioneering designs in EUV lithography, Generation III night vision systems, high performance targeting FLIRs, prototype HMDs with binary optics, and many others. His service to the optics community includes a key optical design role in developing the optical tests for the all of the new mirrors used in the COSTAR and WF/PC II instruments in the first Hubble Servicing Mission in addition to his earlier work on the Space Telescope Fine Guidance System. Dr. Thompson has authored numerous papers for SPIE conferences and served as a conference cochair and proceedings coeditor for the 1998 International Optics Design Conference, cosponsored by SPIE.
