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 […]

New Optics for Astronomical Polarimetry

Summary New optical technologies are revolutionizing astronomical polarimetry by expanding the range of polarization optics for telescopes and scientific imaging. Liquid crystal retarders, including nematic liquid crystals and ferroelectric liquid crystals, offer electrical control of polarization with low voltage and fast response times, making them ideal for adaptive optics and infrared imaging. Polymer retarders provide […]
