Abstract
The development of Fiber Bragg Gratings (FBGs) is closely associated with the field optical fiber sensors. This chapter presents a personal overview of the history of FBGs, with particular emphasis on the interrelation and impact of FBGs with sensing. The major milestones for FBG-based sensing are identified, from the very discovery of fiber gratings to current developments that are described in full detail in the following chapters of this book.
