Journal ArticleDOI
Optical coherence-domain reflectometry: a new optical evaluation technique.
TL;DR: An optical evaluation technique is described that is suitable for determining the positions and magnitudes of reflection sites within miniature optical assemblies using the coherence effects exhibited by a broadband optical source and is referred to as optical coherence-domain reflectometry.
Journal Article
Coherent optical-fibre sensors with modulated laser sources
TL;DR: In this paper, the authors describe a system whereby source modulation may be used to determine the state of a remote interferometer accurately and unambiguously over phase modulations from a fraction of an optical wavelength to tens or even hundreds of wavelengths.

Journal ArticleDOI
OFDR diagnostics for fibre and integrated-optic systems
S.A. Kingsley,D.E.N. Davies +1 more
TL;DR: Optical frequency-domain reflectometry shows promise as a diagnostic tool for high-resolution ranging in fibre/integrated-optic systems, and in high- resolution distributed fibre-optics sensors.
Journal ArticleDOI
Method of phase-modulating signals in optical fibres: application to optical-telemetry systems
D.E.N. Davies,S.A. Kingsley +1 more
TL;DR: By attaching a piezoelectric transducer that modulates the mechanical tension over a short section of optical fiber, signals in optical fibres are phase modulated as mentioned in this paper, which is applicable to a I-way optical telemetry system.
