Reliably measuring the polarization state of light is crucial for various technological applications, ranging from optical communication to biomedical imaging. Yet conventional polarimeters are made ...

Controlling both the state and degree of polarization of light is a long-standing challenge in optics. While metasurfaces offer compact, high-resolution control over wavefronts, most existing designs ...

Researchers from Jinan University, under the direction of Professor Yanjun Bao and Baojun Li, developed a novel metasurface-based imaging method that allows for the simultaneous measurement of ...

Polarimetric imaging can uncover features invisible to human eyes and conventional imaging sensors, hence is becoming an ever more essential technique in modern society. Conventional polarimetric ...

Polarization of light can reveal otherwise invisible information about natural materials and the condition of man-made structures, but the cameras used to detect it are often bulky, expensive, and ...
