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.

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.

Optical fibers and their applications
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract Fiber optics have become in the last few years an extremely attractive method of data transfer. A short review of their properties and of their applications is given, together with some feelings from personal experience of the author.

SPIE Proceedings, 2013
In this work an integrated tunable optofluidic liquid core-liquid cladding (L2) optical fiber is presented. The device has been realized by exploiting an innovative three-dimensional hydrodynamic focusing scheme. A tunable circular liquid core has been obtained that is located in the center of the channel, regardless of the flow rate ratio of the ...

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
