The researchers showcase swept-coded aperture real-time femtophotography—an all-optical single-shot computational imaging modality at up to 156.3 trillion frames per second—video-records transient absorption in a semiconductor and ultrafast demagnetization of a metal alloy.

Mueller matrix microscopy is capable of mapping tissue architecture at the subcellular level. Wan, Dong and colleagues report an unsupervised learning approach to identify pathological structures by clustering polarization features in Muller matrix images. This approach enables the identification of microstructures subtypes invisible in nonpolarized optical images.

Polarization-modulated fluorescence microscopy provides molecular orientation mapping in cells.

Revealing the molecular orientations of anisotropic materials is desired in materials science and soft-matter physics. Now, an optical diffraction tomographic approach enables the direct reconstruction of dielectric tensors of anisotropic structures in three dimensions.
