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.

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 ...

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 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.
