Optical fiber uses this reflection to "trap" fiber in the core of the fiber by choosing core and cladding materials with the proper index of refraction that will cause all the light to be reflected if the angle of the light is below a certain angle. fiber optic sensors namely reflectometric and interferometric fiber opt c sensors. Jose Miguel Lopez-Higuera: Handbook of Optical Fiber Sensing Technology, John Wiley & Sons, 2002. Radiation absorption creates electronic excited states that are trapped by localized defects for extended periods of.
