Birefringence polarized light microscopy
Did you know?
WebThis condition is known as birefringence. Polarized light microscopy produces images by utilizing the interference of the split light rays as they re-assemble along the same optical path. The split rays travel at different speeds through the specimen and one ray is retarded with respect to the other. This optical condition is known as retardation. WebFeb 6, 2024 · Optical microscopy is a simple non-contact method ideal to observe in situ the response of ferroelastic domain walls to temperature [44–48], electric field [48–61] or stress [62, 63].In transmission, the use of crossed-polarizers, combined with a spatial resolution of the order of a half wavelength of light, produces high-contrast images of the …
