A compact anisotropic laser-feedback polarimetry setup enables self-calibrating, dual-parameter birefringence measurement. The system retrieves phase retardance and fast-axis azimuth simultaneously, ...
Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by ...
When stars die out, they emit gamma-ray bursts. Although scientist can calculate the explosion energy from dying stars, it is difficult to do when the conversion efficiency is low or unknown. Using ...
