Optical Anisotropy in Ramie FibersPhysics Department, Faculty of Science, Mansoura University, Egypt
Physics Department, Faculty of Science, Mansoura University, Egypt Multiple beam Fizeau fringes in transmission and at reflection were used to de termine several optical properties of ramie fibers: the refractive indices of the fiber for monochromatic light vibrating parallel and perpendicular to the fiber axis and the birefringence of the fibers. A new method was used to determine these quantities by regarding the area enclosed by the deviation of the fringe as it crosses the fiber as representative of the path-difference integrated across the fiber.
