The apparatus includes a polarization scrambler to insure that the interfering signals traversing the alternative optical paths interfere with their respective polarization states aligned. The use of the polarization scrambler together with recordation of the maximum multiple path interference measured over a pre-selected time interval provides a value of multiple path interference most representative of the performance of the part of an optical waveguide circuit under test.

摘要： A fiber optic fault detector and generic fiber optic sensor system (100)for detecting breaks in an optical fiber using a low coherence interferometric technique. The system comprises a light source (102) configured to produce light traveling along the optical path, a modulator optically coupled to the light source configured to modulate at least a portion of the light as a function of a modulation signal (128), a detector optically coupled to the modulator configured to produce a detector output based upon a sensed intensity of the light, and an electronic array configured to receive the detector output and determine the optical fault. The low coherence interferometric technique allows for detection of a fault in the fiber with a minimal amount of test equipment and with higher measurement sensitivity and resolution. The system may alternatively include a transducer, positioned in place of the fiber under test (150), having a response which changes in reflective or optical path length. The system can be used in a LIDAR system, wherein telescope optics are used in place of the fiber under test (150), to transmit light and collect light scattered from objects or from the air.

摘要： In optical media (e.g., an optical fiber) having first and second order polarization mode dispersion, the relationship between the polarization mode dispersion and the change in the measured averaged state of polarization of an optical signal in the media as a function of the signal's bandwidth can be predictable. Accordingly, first and second order polarization can be determined by measuring a series of the averaged state of polarization's for an optical signal with varying signal bandwidths.

摘要： A device for measuring the parameters of phase elements and dispersion of optical fibers, characterized in that it contains: at least one light source, serially connected to at least one fiber optic coupler, one of whose arms constitutes a part of the reference arm, and whose second arm constitutes a part of the measurement arm of the device, and at least one motorized linear stage is mounted on at least one arm of the device, and at least one of the arms of the device is connected, either directly, or through an additional fiber optic coupler, to at least one detector, and at least one collimator is placed in at least of the arms of the device, at least before the phase element. A method of measuring the parameters of the phase element and the dispersion of optical fibers, applying the device according the invention, is conducted in at least two stages, wherein the first stage assumes the calibration of the device according to the invention, and the second stage is the proper measurement, characterized in that during calibration of the device according to the invention, light from the low-coherence light source (1.1) is directed to the fiber optic coupler (2.1), where it is separated into two arms: measuring and reference, and then the motorized linear stage(6) moves, recording information on its position until zero difference of optical paths between particular fiber optic coupler arms is obtained. Interference occurs in the fiber optic coupler(2.2), after passing through collimators (3.2) and (4.2), and interferogram is collected in time delay, which translates into motorized linear stage movement. Inteferogram is collected by a photodetector, in particular by a photodiode, and after the device is calibrated, the system proceeds to proper measurement, in which a phase element, particularly a lens intended for measurement, is inserted in the measurement arm of the device according to the invention, between the collimators (3.1) and (3.2), after which, sliding the motorized linear stage, the position producing zero optical path difference is determined, and the thickness of the phase element is determined on the basis of the differential position of the equivalent optical path in the calibration measurement and the proper measurement with the phase element, and basing on the knowledge of the refractive index of the glass the lens was made of.

摘要： The present invention provides novel apparatus and methods for fast quantitative measurement of perturbation of optical fields transmitted, reflected and/or scattered along a length of an optical fibre. The present invention can be used for point sensors as well as distributed sensors or the combination of both. In particular this technique can be applied to distributed sensors while extending dramatically the speed and sensitivity to allow the detection of acoustic perturbations anywhere along a length of an optical fibre while achieving fine spatial resolution. The present invention offers unique advantages in a broad range of acoustic sensing and imaging applications. Typical uses are for monitoring oil and gas wells such as for distributed flow metering and/or imaging, seismic imaging, monitoring long cables and pipelines, imaging within large vessel as well as for security applications.

摘要： A device for performing polarization mode dispersion (PMD) measurements of an optical fiber is disclosed. The PMD measurement device employs a fixed analyzer method, and includes a tunable Fabry-Perot inferometer as the wavelength-selective element and an optical bandpass filter for spectrum calibration. A novel scanning algorithm, which performs multiple scans at different velocities, enables accurate PMD measurements, even of moving optical cable. The tunable Fabry-Perot interferometer is able to scan over a wide wavelength range and yet have a narrow linewidth, such that a wide range of PMD values can be measured.
