      Miniature endoscopic optical coherence tomography for calculus detection

      The effective treatment of periodontitis involves the detection and removal of subgingival dental calculus. However, subgingival calculus is more difficult to detect than supragingival calculus because it is firmly attached to root surfaces within periodontal pockets. To achieve a smooth root surface, clinicians often remove excessive amounts of root structure because of decreased visibility. In addition, enamel pearl, a rare type of ectopic enamel formation on the root surface, can easily be confused with dental calculus in the subgingival environment. In this study, we developed a fiber-probe swept-source optical coherence tomography (SSOCT) technique and combined it with the quantitative measurement ...

    2. Quantitative Phase Imaging With Swept-Source Optical Coherence Tomography for Optical Measurement of Nanostructures

      Quantitative Phase Imaging With Swept-Source Optical Coherence Tomography for Optical Measurement of Nanostructures

      In this letter, a phase-sensitive, swept-source optical coherence tomography (SS-OCT) system is implemented for the optical measurement of nanostructures. A new approach is proposed to reduce the phase errors, resulting from trigger jitter of the swept source and the asynchronization between the A-scan trigger and OCT signal at the data acquisition end, with a narrowband fiber Bragg grating to generate the accurate A-scan trigger. Furthermore, combining the common-path configuration with the proposed approach, the displacement sensitivity can be calculated to be 80 pm when the swept source is operated at 30 kHz. Finally, the conducting glass was scanned with the ...
