    • Electronic device for automatic calibration of swept-source optical coherence tomography systems 
      Hoyos, Sebastian; Pacheco Barajas, Oscar Joseu; Zavareh, Amir Tofighi (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2021-07-06)
      A circuit for generating a swept source optical coherence tomography (SS-OCT) imaging calibration clock. The circuit comprises a first photodetector configured to convert an SS-OCT optical calibration signal to an SS-OCT ...
    • Method and apparatus for frequency encoded ultrasound-modulated optical tomography of dense turbid media 
      Wang, Lihong (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2000-03-21)
      An apparatus (10) for frequency encoded ultrasound modulated optical tomography is provided. A function generator (12) produces a frequency sweep signal which is applied to an ultrasonic transducer (20). The ultrasonic ...
    • Method and apparatus for obtaining information from polarization-sensitive optical coherence tomography 
      Wang, Lihong; Jiao, Shuliang (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2005-11-01)
      An apparatus includes a first section operable to detect polarization-sensitive radiation emitted by an object, and a second section operable to determine a Jones matrix based on information obtained by the first section ...
    • Short-wavelength coherence tomography 
      Paulus, Gerhard Georg; Rodel, Christian (United States. Patent and Trademark Office; Texas A&M University. Libraries, 2010-02-02)
      The present relates generally to methods, systems and apparatuses for three dimensional and cross-sectional imaging of objects (e.g., silicon) and subjects at a nanometer-scale resolution using short wave-length (e.g., ...
