摘要： An optical sensor includes elongate light transmission means such as an optical fibre (13). A lens (16) of at least nearly half-pitch length is positioned with one of its focal planes substantially at a mouth (13a) of the optical fibre to receive and focus a diverging cone of light emergent therefrom. A reflector (20) is disposed substantially at another focal plane of the lens to reflect the focused light back to the mouth of the fibre. Detection means (14) in the path of the light between the mouth and the reflector is arranged to influence the light in response to an external condition in a manner whereby the reflected light received back at the fibre mouth may be monitored to detect the influence and thereby the condition. An optical fibre network has an incident fibre (40) and a detection fibre (42) coupled to plural optical components (60) via respective optical fibres (62) associated with the components and one or more optical fibre couplers (64, 68, 69). The network further includes means (44) to transmit along the incident fibre incident signals of close but discrete wavelengths, and means (82) associated with each of said respective optical fibres (62) to reflect a portion of each of the signals back along the fibre as a respective reference signal.

摘要： A method of fabricating a fused fibre optic coupler includes disposing two or more segments of optical fibre under longitudinal tension. The tensioned fibre segments are preheated to a temperature sufficient to soften the segments and thereby substantially relieve their tension by inelastic stretching of the segments. After the segments have cooled, the fibre segments are re-tensioned and then heated while in intimate side-by-side contact to a temperature sufficient to cause the fibre segments to fuse together.

摘要： A fiber optic sensor for detecting and/or measuring a physical quantity varying at any frequency from a maximum desired frequency down to zero frequency with minimum disturbance from environmentally induced perturbations. A first highly birefringent optical fiber is positioned longitudinally adjacent to a second equally birefringent fiber. Each fiber has orthogonally disposed fast and slow axes. The fibers are oriented such that their fast axes are perpendicular to each other. When subjected to stress caused by a physical quantity acting on the fibers through a transducer, the birefringence of each of the two fibers is asymmetrical altered thereby rotating the states of polarization of coherent light signals passing through the two fibers in a common direction. Environmental perturbations symmetrically alter the birefringence of each of the fibers thereby rotating the states of polarization of the light signals in opposite directions. The states of polarization of the light signals emanating from the two fibers are detected and combined such that the changes due to the physical quantity enhance each other while the changes due to environmental perturbations are cancelled.

摘要： A Sagnac rotation sensing interferometer that uses a Mach-Zehnder interferometer to provide incident light beams that counter-propagate through an optical-fiber loop. The Sagnac interferometer operates at maximum sensitivity for zero rotation rates when the Mach-Zehnder is adjusted so that the intensities of the incident light beams are equal. By peiodically varying the position of a mirror in the Mach-Zehnder the interferometer is switched into and out of quadrature so that the amplitude of the interferometer output signal is modulated at frequency f.sub.o. Phase sensitive detection at 2f.sub.o or multiples thereof reduces the background noise level several orders of magnitude below the level for dc operation.

摘要： An acousto-optic frequency shifter in which two cylindrical acoustic resonators driven 90.degree. out of phase from one another are placed around a birefringent, single-mode optical fiber approximately three-quarters of a polarization beat length apart. The resonators interact with optical radiation propagating in one of two polarization modes of the fiber, the first to cross-couple two sidebands into the other polarization mode, and the second to suppress one of the sidebands in the cross-coupled mode and enhance the other, thereby creating a single sideband signal completely within the fiber.

摘要： A sensor is provided for sensing or detecting the presence of an environmental field condition such as acceleration, temperature change, magnetic or acoustic fields. The field is sensed by interference between two mutually orthogonal polarized eigenmodes in a single monomode optical fiber which may be disposed either linearly or wound on a mandrel made of compliant material for sensing an acoustic field, or made of magnetostrictive material for sensing a magnetic field. Polarized light propagated through the optical fiber is detected at its outlet independent of environmentally induced low frequency variations whereby the sensor may be maintained at quadrature and maximum sensitivity.

摘要： A fiber-optic gyroscope designed to operate at maximum sensitivity by suping two equal-intensity input beams with a specific phase difference to the gyroscope optical coupler. When the coupler outputs into the gyroscope optical fiber coil are of equal intensity, reciprocity requires the gyroscope to operate at quadrature. This device is realized by splitting a laser beam into two paths with a phase shifter in one of the paths to control the phase shift and thereby the intensity of the beams, and coupling the light from these paths into a fiber optic coil via a four-port 3dB coupler.

摘要： An interferometric fibre optic network includes a downlead optical fibre (12) and a pair of uplead optical fibres (14, 16). Sites for a plurality of interferometric sensor pairs (25) are arranged whereby each pair (25) is optically connected in use of the network to the downlead and uplead fibers (12, 14, 16) via a 3.times.3 fibre optic coupler (30) and respective further fibre optic couplers (32) on the uplead fibres (14, 16). The uplead fibres (14, 16) are multimode optical fibres, and each of the 3.times.3 couplers (30) is optically connected to the respective further couplers (32) by a single mode optical fibre (34). The further couplers (32) are asymmetric couplers having high tap-on coupling from the single mode optical fibre (34) to the respective uplead fibre (14, 16) but low tap-off coupling from the uplead fibre (14, 16).
