A holographic matched filter is used to measure the changes in the output of a dual-mode
fiber undergoing axial strain. The hologram is formed by interfering collimated light from a …

The principle of a fiber sensor based on an optical correlation technique is described and
assessed for its feasibility. The device measures the correlation between the far-field …

A novel holographic system is described, in which the functions of all the conventional
optical components commonly used to produce holograms-such as beam splitters, mirrors …

We propose what we believe is the first all-optical fiber sensing system without any
electronic processing. A multiple-mode fiber detects external perturbations and serves as a …

Two dual-mode fibers in tandem act as unbalanced sensor and recovery interferometers.
We investigate how coherence-tuned interrogation of the remote sensor fiber is affected by …

The use of fiber optics in the field of optical holography is described with emphasis on an
experimental arrangement whereby several object and or reference beams are …

A passive self-referencing all-fibre technique for Bragg wavelength shift detection using a
biconical fibre filter is described. This filter, basically a tapered depressed-cladding fibre …

biconical fibre filter is described. This filter, basically a tapered depressed-cladding fibre …

In 1978. KO Hill and colleagues 1 reported the formation of refractive index gratings in
germanosilicate core, silica clad fibers by injection of 488 and 514.5 nm argon-ion laser …

Experimental methods for the practical implementation of few-mode elliptical-core sensors
are described. Techniques for desensitizing the lead-in and lead-out fibers are discussed …
