Abstract
The field of fiberoptic gyroscopes, FOGs, was born after a brief publication by Vali and Shorthill in 1976 proposing the use of a multi-turn, single-mode fiber to enhance the sensitivity of a Sagnac interferometer by the number of turns in the fiber coil. It was this simple concept that encouraged many researchers in universities and in industry to get into this field and to develop fiberoptic gyroscopes for a variety of applications, including high precision ones as needed for navigation. The fortuitous developments that led to the 1976 publication are disclosed to show what really went on behind the scenes during the year preceding this publication.
