  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.
