摘要： A fiber optic sensing coil is formed by winding a non-coated optical fiber in a substantially circular loop. The non-coated optical fiber includes a core and a cladding. Once the non-coated optical fiber is wound, turns of the non-coated optical fiber are fused so that the cladding of the individual turns of the optical fiber are fused to one another at points of mutual contact.

摘要： A fiber optic gyroscope (FOG) including a depolarizer having substantially equal first and second fiber segments of polarization maintaining (PM) fiber coupled to a single mode (SM) fiber loop. The first PM fiber segment includes sections of fiber connected together via a splice having an angle from about 35° to 55° between major axes of polarization of the sections which it connects. Similarly, the second PM fiber segment includes sections of fiber connected together via a splice having an angle from about 35° to 55° between major axes of polarization of the sections which it connects. The length of each fiber section is chosen to maintain the thermal and mechanical symmetry of the SM fiber loop.

摘要： An optical coupler for measuring mean wavelength of a broadband optical source is described. Sensitivity of the optical coupler to variations of refractive index and coupler length is minimized. The sensitivity to the variations of the refractive index is minimized by making a difference between the group refractive indices of the symmetric and asymmetric propagation modes approximately constant and independent of the refractive index. The sensitivity to the variations of the coupler length is minimized by selecting the coupler length that makes output powers from two waveguides to the first order insensitive to its length. This selection is possible for broadband optical sources.

摘要： A fiber optic fault detector and generic fiber optic sensor system for detecting breaks in an optical fiber using a low coherence interferometric technique. The system comprises a light source 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, 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, 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, to transmit light and collect light scattered from objects or from the air.

摘要： A clock system for a fiber optic gyroscope is provided that includes a highly-tunable clock for the bias modulation and a separate asynchronous high-speed clock for the photodetector sampling. By separating the two clocks rather than using two derivatives of the same clock, the clock system and method can provide both the tunability objective of the bias modulation clock and the high-speed objective of the sampling clock, while using readily available, lower performance, radiation-hardened electronics parts.
