The development of techniques for high-speed image acquisition in optical coherence tomography (OCT) systems is essential for suppressing motion artifacts when one is imaging living systems. We describe a new OCT system for performing micrometer-scale, cross-sectional optical imaging at four images/s. To achieve OCT image-acquisition times of less than 1 s, we use a piezoelectric fiber stretcher to vary the reference arm delay. A Kerr-lens mode-locked chromium-doped forsterite laser is employed as the low-coherence source for the highspeed OCT system. Dynamic, motion-artifact-free in vivo imaging of a beating Xenopus laevis (African frog) heart is demonstrated.
在光学相干断层扫描（OCT）系统中，开发高速图像采集技术对于在对活体系统成像时抑制运动伪影至关重要。我们描述了一种新的OCT系统，该系统能够以每秒4幅图像的速度进行微米级的横截面光学成像。为了实现小于1秒的OCT图像采集时间，我们使用压电光纤拉伸器来改变参考臂延迟。一种克尔透镜锁模掺铬镁橄榄石激光器被用作高速OCT系统的低相干光源。本文展示了对跳动的非洲爪蟾心脏进行动态、无运动伪影的体内成像。
