Scientific and Industrial Liquid Crystal Polarimetry Applications
Summary Because the human eye is insensitive to polarization, valuable optical information often goes unnoticed. However, polarimetry—the measurement of a light wave’s polarization state—is crucial in fields such as biology, chemistry, astronomy, and remote sensing. This paper explores methods for accurately determining the retardance value and fast axis position of an unknown waveplate and highlights […]
