FOA Lecture 23: Total Internal Reflection in Optical Fiber

FOA Lecture 23: Total Internal Reflection in Optical Fiber

This is Lecture 23 in the Fiber Optics Association's series of lectures on fiber optics. In this lecture, the presenter discusses "refraction" and "total internal reflection," the optical terms for how light is bent or reflected at the boundary of two different materials. Total internal reflection is important in fiber optics as it is the reason that light can be trapped in the core of the fiber, making optical fiber transmission possible. Using a visible red laser from a VFL, the video demonstrates total internal reflection in a large core plastic fiber. Running time for the lecture is 5:03. Flash is required to view the video.
