Abstract

We present, for the first time to our knowledge, a new fiber gyroscope scheme based on an optoelectronic oscillator OEO. The OEO is modified by adding another fiber loop in such a way that the new scheme is composed of an all optical "AO" cavity coupled to an optoelectronic "OE" cavity. The new optoelectronic fiber gyroscope OEFG is capable of not only measuring the angular rotation speed but also of determining the direction of rotation which is not possible in existing fiber laser gyroscopes without the inclusion of complicated setup..
