摘要： An apparatus and method for using a counter-propagating signal method for locating events is disclosed. The apparatus and method uses a Mach Zehnder interferometer through which counter-propagating signals can be launched. If the sensing zone of the Mach Zehnder interferometer is disturbed, modified counter-propagating signals are produced and the time difference between receipt of those signals is used to determine the location of the event. A microcontroller receives feedback signals which adjusts polarization controllers so that the polarization states of the counter-propagating signals can be controlled to match the amplitude and/or phase of the output signals. Detectors are provided for detecting the modified signals.

摘要： A method and apparatus for monitoring a structure and for locating the position of an event including a light source, a waveguide, and a detector means. The waveguide receives light from the light source so that the light is caused to propagate in counter-propagating optical signals in the waveguide. The waveguide includes the counter-propagating optical signals or some characteristic of the signals modified or effected by an external parameter caused by or indicative of the event to provide modified counter-propagating optical signals. The detector means detects the modified counter-propagating optical signals effected by the parameter and determines the time delay or difference between the modified counter-propagating optical signals in order to determine the location of the event.

摘要： A system and method for monitoring a structure and for distinguishing between an alarm condition, and a nuisance event such as rain. An optical fibre sensor (20,22) produces a signal indicative of a disturbance and level crossing rates are determined to distinguish between noise in the signal (nuisance event) and a required event. A FFT technique is also disclosed as well as classification of an event by extracting predetermined features from the signal.

摘要： A modalmetric fibre sensor comprises a multimode sensor fibre (26), a light source (14) for launching light into the multimode fibre (26) to produce a multimode speckle pattern of light at an end of the fibre (26), a single mode fibre (22) to receive light from the multimode speckle pattern and a detector (18) connected to the single mode fibre (22) to detect the received light from the multimode speckle pattern. A connector (33) connects the ends of the multimode fibre (26) and single mode fibre (22) with the end faces (31,32) of the two fibres disposed at an acute single to one another. The light from source (14) may be transmitted to the multimode fibre (26) through the single mode fibre (22) and the end of multimode fibre (26) remote from single mode fibre (22) may be mirrored to reflect light back along the multimode fibre to the single mode fibre which transmits the received light to the detector (18).
