Abstract

Fiber-optic ring structures with multiple recirculations are reviewed and their applications for the accurate measurement of a variety of physical measurants are analyzed. The methods are based on the fact that minute changes in the round trip time around the loop, are amplified after many recirculations, thereby making them measurable quantities. Some new possibilities of measurements are proposed. Analog self-oscillations and optical pulse multiple propagation are considered. Influences of length of fiber, parameters of optical radiation and pulse form on characteristics of such devices are observed.
