Annual Review of Earth and Planetary Sciences, 2021
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.

This paper describes the development of fiber optics technology — an essential element of the telecommunications revolution — and reviews the remarkable progress in fiber design and fabrication, optical amplifiers, UV-induced fiber gratings, novel microstructured optical fibers, and integrated optics. The paper also explores the limits of optical fiber

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 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.
