Birefringence retardation
Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to become lighter or darker through rotation of the polarization (circular birefringence) of linearly polarized light as viewed through a sheet polarizer at the screen's surface. Similarly, light modulators modulate the intensity of light through electrically induced birefringe… WebJul 24, 2024 · c Magnetic-field dependence of the phase retardation and birefringence in the low-field range, 0–200 mT.
