Applying novel detector development based on CMOS technology to Fourier domain optical coherence tomography we achieve depth profile rates up to 200,000 scans/sec. This speed allows for dramatic improvement for imaging small retinal details, such as photo-receptors and capillaries. We demonstrate the impact of this achievable speed to Doppler tomography and discuss advantages as well as short-comings of high speed 3D Doppler imaging of the human retina. Experimental data of 3D static DFDOCT sets from fovea and nerve head region are shown together with first 4D imaging of retinal capillary flow.
将基于CMOS技术的新型探测器开发应用于傅里叶域光学相干断层扫描，我们实现了高达200,000次扫描/秒的深度剖面速率。这种速度极大地改善了对视网膜微小细节（如光感受器和毛细血管）的成像。我们展示了这种可实现的速度对多普勒断层扫描的影响，并讨论了人体视网膜高速三维多普勒成像的优点和缺点。展示了来自中央凹和神经头区域的三维静态DFDOCT数据集的实验数据以及视网膜毛细血管血流的首次四维成像。
