We developed an ultrahigh-resolution full-field optical coherence tomography (FF-OCT) microscope that is based on the spatial, rather than the temporal, coherence gating. The microscope is capable of observing three-dimensional microbiological structures as small as 0.4 μm × 0.4 μm × 1.0 μm (xyz) using quasi-monochromatic light and a liquid crystal retarder. Unlike traditional FF-OCT systems, this microscope can be operated in high resolution for any preferable wavelength with minimized defocusing and dispersion effects. High-resolution images of an onion cell are presented.
我们开发了一种基于空间相干门而非时间相干门的超高分辨率全场光学相干断层扫描（FF-OCT）显微镜。该显微镜使用准单色光和液晶延迟器能够观察到小至 0.4μm×0.4μm×1.0μm（xyz）的三维微生物结构。与传统的 FF-OCT 系统不同，该显微镜可以在任何优选波长下以最小的离焦和色散效应进行高分辨率操作。本文展示了洋葱细胞的高分辨率图像。
