• 論文の詳細を見る

• This study proposes a new approach to improve the phase stability for swept-source optical coherence tomography (SS-OCT) with single-channel acquisition. This approach can improve the phase instability due to the A-scan trigger jitter from the swept source, or the asynchronization between the A-scan trigger and high-speed digitizer, which enables the visualization of vascular structures by SS-OCT. Aside from reducing the phase noise of the OCT system, only one channel is required for the A-scan trigger, data storage, and wavelength calibration by implementing the proposed approach. Finally, human skin was scanned <i>in vivo</i> to demonstrate the vascular images.
