Polarimetry as a research area focuses on the measurement, analysis, and interpretation of the polarization state of electromagnetic radiation to infer physical properties of sources, media, and interfaces. It encompasses development of polarimetric instrumentation, calibration methods, and data reduction algorithms, and is applied across wavelengths from radio to X-rays. Research topics include Stokes parameter retrieval, Mueller and Jones matrix characterization, depolarization mechanisms, and polarimetric imaging. Polarimetry is used to probe anisotropy, magnetic fields, scattering geometries, surface roughness, particle size and shape distributions, as well as to enhance contrast and classification in remote sensing, astrophysics, materials science, and biomedical optics.
