Abstract With the development of low loss single mode optical fiber waveguides, it is possible to construct a gyroscope using optical fibers. The configuration is a multi-turn Sagnac interferometer. Light from an external source is split and injected into the fiber ends, travels in clockwise and counterclockwise directions and is recombined to form ...

Publisher Summary This chapter focuses on silica-based optical fibers, which are the most important transmission media for long-distance and large-capacity optical communication systems. A distinguishing feature of these optical fibers is their low loss characteristics.

International audience; Optical fibers are dielectric waveguides that transport light between two points. They are usually made of high-purity glasses. It is well known that light travels in a straight line in free space but when light is trapped in an optical fiber, it can propagate with bends and can carry information anywhere from a few meters to ...

Optical Fibers for Fiber Optic Gyroscopes
2019With the possible exception of nonsilica glasses, each time a new fiber technology has emerged, someone has applied it to FOGs and reported beneficial results. The development of the FOG has essentially tracked that of commercial optical fibers for more than 40 years, running parallel since 1976, when Vali and Shorthill first demonstrated the concepts ...

Optical fiber is now the backbone of present days’ telecommunications network. The basic fiber material is high purity silica glass. Most of the technologies are now perfected and research is now directed towards new highly transparent materials for getting large bandwidth.

The engeneerized prototipe of a fiber-optic sensor useful for vibration measurement in hostile environments is presented.The vibrometer is essentially based on a "differential" heterodyne Michelson-type interferometer in which the reference beam and the sensing beam are both guided, with orthogonal polarization, by the same single-mode polarization ...

In the following sections, we shall discuss a variety of field and laboratory measurements on telecommunication fibers, largely excluding sources, detectors and electronics. Certain of these measurements, especially bandwidth and attenuation, will often yield different results for different launching conditions.

In this paper we describe how the art of weaving can be applied to fiber optics in order to produce precisely controlled reproducible image guides and image dissectors. As examples of the types of device for which woven fiber optics are applicable, we describe a 3:1 interleaver for use with a cathode-ray tube to produce color images, and a high speed ...

A small-diameter jet of a transparent liquid having a refractive index greater than the surrounding medium can entrap a light beam and act as an optical fiber. The liquid stream can be bent through quite large angles and will still retain the light.
