摘要： PROBLEM TO BE SOLVED: To disclose an accelerometer for measuring acceleration and a manufacturing method of accelerometers. SOLUTION: In one embodiment, the accelerometer is provided with a frame, a mass movably suspended from the frame, a fixing element having a circular surface and immovable with respect to the frame, a movable element having a circular surface and movable with the frame, and a detection coil of an optical waveguide wound on the circular surfaces for detecting the movement of mass, corresponding to the acceleration on the basis of detection results of changes in the length of the detection coil by an interferometer. The accelerometer manufacturing method includes both a step of suspending the mass in the frame and a step for winding the optical waveguide on the circular surfaces. The sensitivity of the accelerometers and their low manufacturing cost enable them to be used for incorporating into ocean bottom cables for earthquake monitoring and prediction. The accelerometers can be used as inline accelerometers or crossline accelerometers. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： The invention relates to a method of interrogating an interferometric optical fibre sensor system. The system comprises a laser source for generating interrogation light and an sensor array with at least a first and a second reflector and with a sensor delay being a difference in propagation time for light being reflected from the first and second reflector, respectively. The method comprises continuously and repeatedly frequency sweeping the interrogation light from the laser source within a sweep bandwidth, SBW , over a sweep duration, t sw , with a substantially constant sweep rate r = SBW / t sw , to produce a swept interrogation light signal. The swept interrogation light signal is launched into the sensor array. The method further comprising detecting reflected signals being returned from the sensor array by each of the reflectors, respectively, wherein detection comprises mixing a return light signal from the array with a local oscillator, LO, signal onto an optical receiver to produce an electrical radio frequency signal. The electrical radio frequency signal is then demultiplexed into a first and second signal channel, corresponding to the first and second reflector, respectively. Each of the first and second signal channel are demodulated into a first phase response from the first reflector and a second phase response from the second reflector. Finally, the method comprises subtracting the first phase response from the second phase response to obtain a sensor phase signal. The invention further relates to an interferometric optical fibre sensor system.

摘要： The invention relates to a hydrophone housing. The housing comprises an outer casing with an exterior shape being in close contact with sediment when buried therein and having a deflectable wall part. Solid material partly fill the casing to define an outer chamber behind the deflectable wall part, a cavity shaped so that an inner chamber is defined immediately surrounding a hydrophone sensing element held therein, and a first duct for liquid connection between the outer chamber and the cavity or an internal volume of the hydrophone sensing element. Thereby, a hydraulic coupling is provided so that an acoustic pressure causing small radial displacements of outer surface of the housing will, via liquid in the first duct, cause large radial displacements of the hydrophone sensitive element. The area of the deflectable wall part is much larger than the area of the sensitive element so that only small displacements of the housing are required to cause large displacements at the hydrophone sensing element.

摘要： An optical waveguide Bragg grating fabrication apparatus comprises a light source providing ultra-violet(UV) light and optical means for adapting the light beam to form an interference pattern in a photosensitive optical waveguide. The interference pattern has a spatial intensity modulation along the length of the optical waveguide and thus providing an optical grating in the waveguide in the form of a refractive index modulation. The optical means comprises a movable non-uniform diffractive mask for dividing the optical beam in at least two beams and optical elements for collecting two or more of the light beams to interfere on the optical waveguide. The optical means comprises position control means for controlling the position of at least one mirror or lens. Corresponding methods and the use of a super-periodic diffractive mask in such fabrication are described.

摘要： Method for coating an optical fibre with optical fibre Bragg grating (FBG) with a hermetic coating, particularly a coating of carbon, to avoid ingress of gases, vapours or fluids in the ambient environment. This can be water or hydrogen, which can diffuse into the fibre glass and cause deviation/drift in the measured Bragg measurements. Bragg grating that maintain the grating strength at temperatures in excess of 1000 °C is used, which is heated to above 1000 °C in a chamber with a reactive gas that produces deposition of carbon.
