Abstract
In the past, the interferometric fiber optic gyro (IFOG) has generally been viewed as an angular rate sensor. This may appear true on a coarse time scale. However, a study of its behavior within the transit time of light through the fiber optic coil shows that, in reality, the IFOG is a rate integrating gyro with a very short memory. Making use of fast sampling and accumulation, the rate integrating characteristic can be retained. Mechanized that way Litton IFOG exhibits an output response which is similar to
