Abstract
A method for measuring certain geometrical properties of an optical fiber wherein the coating is removed from adjacent one end of the fiber, a high intensity light source is focused at the bare fiber and coating interface in order to couple scattered light into the optical fiber cladding and the intensity distribution of the transmitted light at the end face of optical fiber is analyzed. In this fashion nonuniformities on the end face of the optical fiber will not substantially affect the accuracy of measurements of geometrical properties of the cladding region of the optical fiber.
