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 […]

Liquid Crystal in Precision Optical Devices

Summary While liquid crystal technology is widely known for display applications, its role in scientific and engineering fields is rapidly expanding. Liquid crystal devices (LCDs) are now critical for beam steering, wavefront modulation, and polarization switching in precision optical systems. Unlike traditional flat-panel displays, high-performance liquid crystal optics require specialized construction techniques to achieve superior […]
