Microbending effects in singlemode optical fibers: investigation and novel applications
(Virginia Tech, 1994-12-04)
<p>Microbends are axial distortions on the optical fiber that have a spatial wavelength small enough to effect coupling between guided and radiation or cladding modes. The magnitude of this wavelength-dependent coupling ...
Sapphire optical fiber sensors
(Virginia Tech, 1991-05-05)
<p>Fiber optic sensors offer many advantages over conventional sensors, including; small size, low weight, high strength and durability. Standard silica optical fibers are limited by the material properties of silica. ...
Concentric-core optical fiber sensors
(Virginia Polytechnic Institute and State University, 1986)
This thesis describes the implementation of a mechanical strain sensor which uses concentric core optical fiber waveguide as the sensing element. When this particular type of fiber is strained, a transfer of optical power ...
In-line optical fiber holography
(Virginia Tech, 1990)
Improvements in fiber optic coupler fabrication techniques
(Virginia Tech, 1994)
Soliton Propagation in nonlinear optical fibers: theory and application
(Virginia Tech, 1987-12-17)
<p>A survey of research in nonlinear optical fibers is given. Important background concepts are introduced and explained. Present and future applications of nonlinear optical fibers arc reviewed. A mathematical model of ...
Temperature corrected strain measurements using optical time domain reflectometry
(Virginia Tech, 1990-05-12)
<p>A method of using optical fiber to measure strain and correct for the effects of temperature is proposed. A means of measuring apparent strain is given, pure temperature is measured using Fresnel-backscatter based Optical ...
Overview of fiber optics technology: industrial and military
(Virginia Tech, 1989-03-05)
Fiber optics technology is being used in many applications, both in the military world and in the industrial world. A broad overview of this technology is provided, including a discussion of the fundamentals of fiber ...
Improved draw process in optical fiber fabrication
(Virginia Tech, 1994)
High resolution optical time domain reflectometry and its applications
(Virginia Polytechnic Institute and State University, 1988-01-15)
High resolution Optical Time Domain Reflectometry (OTDR) measurements have recently allowed spatial resolutions of less than one millimeter. These capabilities indicate that OTDR techniques may be suitable for non-conventional ...
