论文摘要
光学衍射断层扫描（ODT）是一种三维（3D）无标签的成像技术。样品的3D折射率分布可以通过ODT从多个二维光场图像重建。本文中，我们使用铁电液晶空间光调节剂（FLC SLM）引入了一种暂时的低碳ODT技术。 FLC SLM提供的快速二进制调制可确保高时空分辨率，并具有大大减少相干噪声。我们使用各种样品（包括胶体微球和活细胞）证明了拟议系统的性能。
Optical diffraction tomography (ODT) is a three-dimensional (3D) label-free imaging technique. The 3D refractive index distribution of a sample can be reconstructed from multiple two-dimensional optical field images via ODT. Herein, we introduce a temporally low-coherence ODT technique using a ferroelectric liquid crystal spatial light modulator (FLC SLM). The fast binary-phase modulation provided by the FLC SLM ensures a high spatiotemporal resolution with considerably reduced coherent noise. We demonstrate the performance of the proposed system using various samples, including colloidal microspheres and live epithelial cells.
