    1. Systems and methods for improved OCT measurements

      Systems and methods for improved OCT measurements
      Various systems and methods for sequential angle illumination to achieve ultra-high resolution optical coherence tomography (OCT) images. One example OCT system includes a light source, a beam divider, sample arm optics, a detector, and a processor. The light source generates a light beam to illuminate the sample. The beam divider separates the light beam into reference and sample arms. The sample arm optics sequentially illuminates a location in the sample ...

    2. Self-referenced optical coherence tomography

      Self-referenced optical coherence tomography
      Systems and methods that use interference signal from a sample tissue (e.g. retina) obtained in a self-referenced manner to obtain one or more characteristics about the sample tissue, such as thickness and intensity information, are discussed in the present disclosure. One example method of analyzing the sample tissue using an interferometry system includes illuminating the sample tissue with a beam of light using a spectrally broadband source. Scattered light ...

    3. Efficient interferometer designs for optical coherence tomography

      Efficient interferometer designs for optical coherence tomography
      Efficient interferometer designs for optical coherence tomography (OCT) systems are presented. One example interferometer design includes two polarization dependent beamsplitters and a non-polarization dependent combiner. The first polarization dependent beamsplitter transmits light in a first polarization state to a sample arm of the OCT system and transmits light in a second polarization state different from the first polarization state to a reference arm of the system. The second polarization dependent ...

    4. Line-field holoscopy

      Line-field holoscopy
      A novel imaging method, line-field holoscopy is presented. A line of light is projected across an object to be investigated through an imaging system. The light scattered from the investigated object is combined with reference radiation. The combined light is projected onto a detector providing a confocal restriction in one dimension. Astigmatic optics in the return path transform the light asymmetrically such that at the detector, the line focus is ...
