Intrinsically anisotropic 1D NbTe4 for self-powered polarization-sensitive photodetection

NPG Asia Materials
Polarization-sensitive photodetection enhances scene information capture, crucial for modern optoelectronic devices. One-dimensional (1D) materials with intrinsic anisotropy, capable of directly sensing polarized light, are promising for such ...

Directional Applicability Analysis of Albedo Retrieval Using Prior BRDF Knowledge

Remote Sensing
Surface albedo measures the proportion of incoming solar radiation reflected by the Earth’s surface. Accurate albedo retrieval from remote sensing data usually requires sufficient multi-angular observations to account for the surface reflectance ...

Polarimeter for Detection of Anisotropy from Reflectance

Polarimetry is used to determine the Stokes parameters of a laser beam. Once all four S0,1,2,3 parameters are determined, the state of polarisation is established. Upon reflection of a laser beam with the defined S polarisation state, the directly measured S parameters can be used to determine the optical properties of the surface, which modified the S-
