Phys.org  May 2, 2024 When light scatters off an object, its polarization, in general, changes—a transformation described by the object’s Mueller matrix. Mueller matrix imaging is an important technique in science and technology to image the spatially varying polarization response of an object of interest, to reveal rich information otherwise invisible to traditional imaging. An international team of researchers (USA – UC San Diego, Germany) conceptualized, implemented, and demonstrated a compact Mueller matrix imaging system—composed of a metasurface to produce structured polarization illumination and a metasurface for polarization analysis—that could, in a single shot, acquire all 16 components of an […]
