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 ...

Distributed acoustic sensing (DAS) is an emerging technology that repurposes a fiber-optic cable as a dense array of strain sensors. This technology repeatedly pings a fiber with laser pulses, measuring optical phase changes in Rayleigh backscattered light.

SPIE Proceedings, 1984
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 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.

Methods of controllable, noncontact rotation of optically trapped microscopic objects have garnered significant attention for tomographic imaging and microfluidic actuation. Here, we report development of a fiber-optic spanner and demonstrate controlled rotation of smooth muscle cells. The rotation is realized by introducing a transverse offset between

A state of the art review of nonsilica based infrared fibers is presented. Two types of fiber materials have been investigated--crystals and glasses. Crystal fiber work appears to be focused on development of short haul CO/sub 2/ laser power delivering lines at 10.6 µm.

A polychromator has been designed and built to obtain time dependent profiles of spectral lines produced in a pulsed plasma. Light intensity is measured simultaneously at ten wavelengths, spaced 1 A apart, by means of a specially constructed fiber optic device.

Analysis of the geometry of recursive tilings has led to the development of a new class of highly ordered optical composites that exhibit fractal surface character. These objects are, we believe, the first engineered fractal objects. The mathematics of tiling and examples of fractal fiber array devices are reviewed.
