Abstract: Optical coupling systems are used for optical communication, measurement of light, the coupling and decoupling of optical paths, as well as being used as optical heads for optical sensors, or photoelectric switches. This kind of system has an optical fiber bundle (10) comprising a central fiber bundle (11) and a peripheral fiber bundle (12), and a focusing means including a ball lens (20). The optical fiber bundle (10) employs as the central fiber bundle (11) one of two optical fiber bundles forming optical paths independently of each other, and as the peripheral fiber bundle (12) one end of the other optical fiber bundle arranged around the periphery of the central fiber bundle (11), thereby forming a collecting terminal (15). The other ends of both of the fiber bundles are formed independently into separate ends (16). The lens (20) is provided in the vicinity of the terminal (15).

Abstract: A continuous elongate strength member for reinforcing an optical fibre cable consists of an assembly of aromatic polyamide filaments impregnated with a synthetic resin, in which the filaments are individually coated with the resin, and the filaments of at least an outer layer of the assembly are helically stranded. The impregnation is carried out by separating the filaments and immersing them in a low viscosity dispersion of the resin in a liquid medium; the filaments are then stranded, and the resin is cured. Apparatus for manufacturing the strength member and various forms of cable incorporating one or more strength members.

Abstract: An inspection instrument (20) is fabricated with segments (32, 33) of limited controllable flexure disposed between an objective segment (34) and a control head (30). The segments (32, 33) are provided with interior frame members (54, 55) to maintain a generally rigid configuration, the variation in flexure providing a stair-climbing-like capability which is advantageous for clearing obstructions in the area being examined. Articulation in two dimensions is provided within each of the segments (32, 33). Control lines (46) thread through the instrument (20) to contact frame members (54, 55) at distal ends of each of the segments (32, 33) to effect independent pivoting among the segments (32, 33). The proximal ends of the control lines (46) connect with manipulative members (50) in the control head (30) for manual control of the articulation.

Abstract: The aim is to rid oneself of the mechanical imprecisions in a spectrometer comprised of a monochromator (10), of light guides (1100) for light transmission and of a sampling device (1200) for the output slot level. To this effect, the spectral images are sensed by multiple faces adapted to the input spectral image of a light guide and supplied to a sampler (1200). It is the section (1102) of the light guide which is adapted to the sampling device.

Abstract: The invention can be used in the fields of communication, measurement, control and so on for coupling and separating optical paths when optical information signals or the like are optically transmitted and received through paths formed of optical fibers. The optical coupling unit includes a main fiber channel (11) formed of a single fiber or a bundle of fibers, a sub-fiber channel (12) formed of a bundle of many fine fibers. A collected end portion (10A) is formed by setting one end of the sub-fiber channel around the periphery of one end of the main fiber channel, and a separated end portion (10B) is formed by separately setting the other ends of the main and the sub-fiber channels. Thus, the light input from the collected end portion is distributed between the main and the sub- fiber channels and lights input form the separated end portions are collected at the collected end portion.

Abstract: The light emitted by light source is picked up by the optical fibres of a cable (1) grouped in three flat beams (2a, 2b and 2c) of which the alignments of the beginning of the fibres face, through a space (3), the alignments of the beginning of the fibres of three other flat beams (4a, 4b, 4c) from three cables (5a, 5b, 5c), a photoelectric cell being arranged at the end of each of these cables. The propagation of light may be allowed or interrupted in the space (3) by a screen (6) which may be moved under the influence of a mechanical means, for example a membrane manometer. The response of the cells may be used to act on adjusting means; thereby, the pressure in a closure may be kept constant. The device allows to avoid optical systems composed of lenses.
