摘要

光纤压电调制器(PZM)是一种很有前途的高速OCT图像数据采集工具，我们在这里展示了利用PZM推挽操作的高速OCT，它可以提供高达2000次扫描/秒，扫描深度为2.5 mm。在1.3-/spl mu/m波段，轴向分辨率为17 /spl mu/m。提出了一种无运动伪影的人体指尖OCT。

High-speed image data acquisition of OCT utilizing push-pull operation of fiber-optic piezoelectric modulators

A fiber-optic piezoelectric modulator (PZM) is a promising tool for high-speed image data acquisition of OCT. We demonstrate here the high-speed OCT utilizing push-pull operation of PZMs which can provide up to 2000 scan/sec with a scan depth of 2.5 mm. The axial resolution is 17 /spl mu/m for the 1.3-/spl mu/m wavelength. A motion-artifact-free in-vivo OCT of human finger tip is presented.
