基于互补金属氧化物半导体线扫描相机的高速傅里叶域光学相干断层扫描（FD-OCT）在100，000轴向扫描每秒在体内成像的单光谱仪为基础的复共轭伪影去除方法进行了评估。三种不同的相移方法与相同的OCT引擎的性能进行评估，使用修改后的数据采集方案，根据每个相移技术的要求。对于所有测试方法，评估了使用纸板的复共轭伪影图像的抑制率。介绍了其他几个特征，包括附加硬件要求（标准FD-OCT组件之外）列表和每种方法的数据采集方案。显示了人体指垫和指甲的体内全范围图像，并与标准FD-OCT图像进行了比较。此外，提出了以100，000 A-扫描/s的速度获得的无复合共轭物的人视网膜体积。
Single spectrometer-based complex conjugate artifact removal methods are evaluated for in vivo imaging with complementary metal-oxide semiconductor line scan camera based high-speed Fourier-domain optical coherence tomography (FD-OCT) at 100,000 axial scans per second. Performance of three different phase-shifting methods with the same OCT engine is evaluated using modified data acquisition schemes, depending on the requirements of each phase-shifting technique. The suppression ratio of complex conjugate artifact images using a paperboard is assessed for all tested methods. Several other characteristics, including a list of additional hardware requirements (beyond standard FD-OCT components) and data acquisition schemes for each of the methods is presented. In vivo full-range images of human fingerpad and nail are shown and compared with standard FD-OCT images. Additionally, a complex-conjugate-free human retinal volume acquired at the speed of 100,000 A-scans/s is presented.
