Polarization-sensitive intensity diffraction tomography

Professor Chulmin Joo's research team at the Department of Mechanical Engineering introduced a computational microscopy platform capable of producing tomographic birefringence images of optically anisotropic materials. Existing birefringence tomography methods mostly operate on interferometric setups, along with single-scattering models, which limits high-fidelity reconstruction of birefringence information of complex and multiple-scattering objects. The researchers developed a vectorial multiple scattering model as a method to analyze the propagation of light in multiple scattering birefringent objects, and combined it with non-interferometric microscopy setup to enable three-dimensional birefringence imaging of multiple-scattering anisotropic materials. This research was published on May 18, 2023 in the journal Light: Science & Applications (IF 20.257).
