The techniques and components used to measure both linear and circular polarization at wavelengths from 0.3 μm to 20 μm are reviewed. Some emphasis is given to the implementation of polarimetry on the latest generation of large-aperture telescopes and some of the difficulties being encountered are addressed.

His professional expertise encompasses radar remote sensing, radar polarimetry, polarimetric scattering analysis, environmental change detection, polarimetric SAR image analysis for monitoring the planet earth. He and his group have developed “Four-component scattering power decomposition” for the utilization of polarimetric SAR image interpretation, which is one of the essential part of polari...

Sensitive magneto-optical polarimetry was proposed by E. Iacopini and Zavattini in 1979 to detect vacuum electrodynamic non-linearity, particular Vacuum Magnetic Birefringence (VMB). This process is predicted QED via the fluctuation of electron–positron virtual pairs but can also be due hypothetical Axion-Like Particles (ALPs) and/or MilliCharged (MCP). Today ALPs are considered a strong candid...
