A section of a tangent vector bundle is a vector field. In the mathematical field of topology, a section (or cross section) of a fiber bundle is a continuous right inverse of the function. In other words, if is a fiber bundle over a base space, : then a section of that fiber bundle is a continuous map, such that.
An optical fiber (or optical fibre) is a flexible, transparent fiber made by drawing glass (silica) or plastic to a diameter slightly thicker than that of a human hair.ptical fiber is also used in imaging optics. A coherent bundle of fibers is used, sometimes along with lenses, for a long, thin imaging device called an endoscope, which is used to view objects through a small hole. Medical endoscopes are used for minimally invasive exploratory or surgical procedures.
