A team of researchers at the Chinese Academy of Sciences working with a colleague from ShanghaiTech University and another from Zhangjiang Laboratory, has developed a new way to make a laser with light in a wide range of ...
Using the Nanshan One-meter Wide-field Telescope (NOWT), Chinese astronomers have performed multi-color photometric observations of a rapidly rotating magnetic star known as HD 345439. Results of this observational campaign, ...
While conventional photodetectors can only measure light intensity, the light field contains much richer information. This information includes but is not limited to phase, polarization, and spectrum.
