Swept source intraoperative OCT angiography
Journal of Innovative Optical Health Sciences, 2021 To accurately guide surgical instruments during ophthalmic procedures, some necessary intraoperative depth perception is required, which standard surgical microscopes supply limitedly. Intraoperative optical coherence tomography (iOCT), combining optical

1.3 m broadband swept sources with enhanced nonlinear effects
Journal of Innovative Optical Health Sciences, 2023 In this work, a new structure is used to enhance the nonlinear effect in the cavity, which improves the performance of the 1.3[Formula: see text][Formula: see text]m broadband swept source. The swept source adopts a semiconductor optical amplifier (SOA),

Instantaneous complex conjugate resolved spectral domain and swept-source OCT using 3x3 fiber couplers [PDF]
, 2005 We report that the complex conjugate artifact in Fourier domain optical coherence tomography approaches (including spectral domain and swept source OCT) may be resolved by the use of novel interferometer designs based on 3x3 and higher order fiber ...
