High Speed Demodulation Systems For Fiber Optic Grating Sensors

View page
US Patent:
6335524, Jan 1, 2002
Filed:
Oct 21, 1998
Appl. No.:
09/176515
Inventors:
Eric Udd - Fairview OR
Andreas Weisshaar - Corvallis OR
Assignee:
Blue Road Research
International Classification:
G01B 1116
US Classification:
25022718, 25022714, 356 32
Abstract:
Fiber optic grating sensor demodulation systems are described that offer high speed and multiplexing options for both single and multiple parameter fiber optic grating sensors. To attain very high speeds for single parameter fiber grating sensors ratio techniques are used that allow a series of sensors to be placed in a single fiber while retaining high speed capability. These methods can be extended to multiparameter fiber grating sensors. Optimization of speeds can be obtained by minimizing the number of spectral peaks that must be processed and it is shown that two or three spectral peak measurements may in specific multiparameter applications offer comparable or better performance than processing four spectral peaks. Combining the ratio methods with minimization of peak measurements allows very high speed measurement of such important environmental effects as transverse strain and pressure.

Methods And Apparatus For Enhancing Dynamic Range, Sensitivity, Accuracy, And Resolution In Fiber Optic Sensor Systems

View page
US Patent:
6363180, Mar 26, 2002
Filed:
Apr 30, 1999
Appl. No.:
09/303163
Inventors:
Tsutomu Yamate - Brookfield CT
Robert J. Schroeder - Newtown CT
Rogerio T. Ramos - Bethel CT
Eric Udd - Troutdale OR
Assignee:
Schlumberger Technology Corporation - Ridgefield CT
International Classification:
G02B 600
US Classification:
385 12, 385 11, 385 37, 356 355, 356364
Abstract:
Methods for enhancing dynamic range, sensitivity, accuracy, and resolution in fiber optic sensors include manipulating the polarization characteristics of the light entering a fiber optic sensor and/or manipulating the polarization characteristics of the light exiting the sensor before it enters the light detection system. An apparatus according to the invention includes a fiber optic core having one or more gratings written onto it, a light source and a detection system for detecting light transmitted through the grating or reflected by the grating. The light source and the spectral demodulation system may be coupled to opposite ends of the fiber optic (transmission mode) or may be coupled to the same end of the fiber optic through the use of a beam splitter and terminators (reflection mode). Apparatus according to the invention include a polarizer and controller located either between the light source and the fiber or between the fiber and the detection system. Other embodiments of the invention include a depolarizing scrambler before the detection system so that the light entering the detection system is depolarized.

Single Fiber Sagnac Sensing System

View page
US Patent:
6459486, Oct 1, 2002
Filed:
Mar 8, 2000
Appl. No.:
09/520771
Inventors:
Eric Udd - Fairview OR, 97024
Michael M. Morrell - Tuscon AZ, 85719
International Classification:
G01B 902
US Classification:
356483, 356478
Abstract:
The system includes a generally broadband, low coherence length light source that injects light into a fiber beamsplitter that is used to generate counterpropagating light beams in a Sagnac loop. The loop includes two facing fiber beamsplitters connected together at differing length inner legs, with one of the output legs of the second beamsplitter usually being connected to an optical fiber that ends with a phase modulator followed by a mirror. Environmental effects at the optical fiber impress relative phase differences between the counterpropagating light beams, which are detected from an interferometric signal that results therefrom.

Fiber Grating Environmental Sensing System

View page
US Patent:
6600149, Jul 29, 2003
Filed:
Dec 22, 2000
Appl. No.:
09/746037
Inventors:
Whitten L. Schulz - Fairview OR, 97024
Eric Udd - Fairview OR, 97024
International Classification:
G01J 142
US Classification:
25022714, 25022716, 385 13
Abstract:
Fiber grating environmental measurement systems are comprised of sensors that are configured to respond to changes in moisture or chemical content of the surrounding medium through the action of coatings and plates inducing strain that is measured. These sensors can also be used to monitor the interior of bonds for degradation due to aging, cracking, or chemical attack. Means to multiplex these sensors at high speed and with high sensitivity can be accomplished by using spectral filters placed to correspond to each fiber grating environmental sensor. By forming networks of spectral elements and using wavelength division multiplexing arrays of fiber grating sensors may be processed in a single fiber line allowing distributed high sensitivity, high bandwidth fiber optic grating environmental sensor systems to be realized.

Appl. No.:
09/520772
Inventors:
Eric Udd - Fairview OR, 97024
Michael M. Morrell - Tuscon AZ, 85719
International Classification:
H04B 1000
US Classification:
398149, 398140, 398141, 398142, 398188, 385 11, 385 32, 385 39
Abstract:
The system includes a generally broadband, low coherence length light source that injects light into a fiber beamsplitter that is used to generate counterpropagating light beams in a Sagnac loop. The loop includes two facing fiber beamsplitters connected together at differing length inner legs, with one of the output legs of the second beamsplitter usually being connected to a in place optical fiber that ends with a phase modulator followed by a mirror. Formatted data is transmitted by impressing relative phase differences between the counterpropagating light beams. Optimum performance depends on appropriate choices for critical lengths in the system.

Differential Fiber Optical Sensor With Interference Energy Analyzer

View page
US Patent:
6795599, Sep 21, 2004
Filed:
Apr 24, 2002
Appl. No.:
10/128847
Inventors:
Vasilii V. Spirin - Ensenada, Baja California, 22860, MX
Mikhail G. Shlyagin - Ensenada, Baja California, 22860, MX
Eric Udd - Fairview OR, 97024
International Classification:
G02B 600
US Classification:
385 12, 385 15, 385 31, 385 37
Abstract:
A fiber optic sensor, which includes an interference energy analyzer, is used to measure strain and temperature distribution along a test fiber. The sensor includes the following: a plurality of double-Bragg grating elements positioned along a test fiber, a broadband light source which produces a broadband spectral profile that propagates along the test fiber, an optical filter that is able to change the parameters of the broadband spectral profile, an optical reflection detector, a fiber optic beamsplitter, and an interference energy analyzer. Each double-Bragg grating element consists of two weak Bragg gratings, separated by a distance unique to each element. The interference energy analyzer calculates the energies of the interference patterns, which are created by beams reflected from double-Bragg grating elements. The energy of the interference signal changes when the gratings in one element non-uniformly change its parameters due to non-equal temperature or strain influence on two gratings.
