Confocal fiber-optic nanobiosensing
2005 Edition, January 1, 2005 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel concept for noninvasive high-resolution confocal biosensing based on simple apertureless fiber-optic confocal designs including either dual-confocal or single-fiber sensor systems is developed. The method can be employed for precise micron/submicron...

Fiber-optic strain gauge
1989 Edition, Volume 7, September 1, 1989 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Prototype fiber-optic strain gauges consisting of plastic fibers containing permanent microbends were fabricated and various properties were measured. Their strain sensitivity as a function of microbend amplitude is shown, and their transduction mechanism, which is primarily...

Fiber optic differential interferometer
2000 Edition, Volume 49, August 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Based on low-coherence interferometry in standard single-mode fibers, a differential interferometer has been proposed. A twin-reflective mirror demodulator was used in the differential interferometer. This interferometer can be used as a fiber optic sensor to measure the...

Interferometric fiber-optic magnetometers
1988 Edition, January 1, 1988 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Fiber-optic magnetometers capable of achieving resolutions of 10/sup -11/ or 10/sup -12/ T are being developed. During initial tests, minimum detectable magnetic signals of <10/sup -10/ T have been demonstrated. These devices use optical-fiber-wound cylinders of...

Coherent fiber optic reflectometer
1990 Edition, January 1, 1990 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel method for measuring the reflection of fiber-optic devices with light carrier frequency dependence such as fiber resonators is proposed. and the design of an experiment based on the proposed principle is described. Results of the measurement of the power...

Fiber optic curvature sensor
2014 Edition, November 1, 2014 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A fiber optic curvature sensor based on discrete Fiber Bragg gratings inscribed in a multi-core fiber is presented. The individual cores of the multi-core fiber are each interrogated by a custom-built spectrometer running at up to 20 kHz. They are interfaced with...

Broadband fiber optic amplifiers
2001 Edition, Volume 2, January 1, 2001 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Broadband fiber optic amplifiers are key elements of DWDM systems and enablers for optical networks. New amplifier technologies for extending gain-bandwidth and equalizing the power deviation among WDM signals are discussed toward the next generation of ultra...

Fiber Optic Cylindrical Diffuser
Fiberguide Industries, Inc.

A fiber optic, cylindrical, light diffuser for medical use includes an unclad distal fiber end where the exposed core end has a conical shape. The core end is enclosed by a sleeve which contacts the clad portion of the fiber only and defines a closed chamber with...

Reliability of Fiber Optic connectors
2010 Edition, September 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Fiber Optic equipment including wet-mate optical connectors is a key part of today's subsea infrastructure in oceanographic, defense and oil and gas applications. For secure communications, high bandwidth applications and large step-out distances fiber optic...

Fiber optic data link development
1991 Edition, January 1, 1991 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Practical design methods for implementing an optimized fiber-optic data link are presented. In addition, the risetime and falltime budgets of the associated components and the overall frequency response of the fiber-optic data link are discussed. All these...
