Abstract: The invention relates to a method and to apparatus for remotely measuring the distribution of a physico-chemical parameter in a medium. The method consists in exciting measurement points (20) situated in a medium (17) in succession via an optical fiber (18), with each point (20) being excited by two light pulses of different wavelengths offset from each other in time occurring simultaneously at said point, each measurement point returning radiation at a third wavelength representative of the temperature of the measurement point. The apparatus includes two lasers (3, 4) emitting different wavelengths, a delay circuit (5) for delaying the light pulse from one (4) of the two lasers, and the measurement points include a material sensitive to biphotonic excitation.

Abstract: Fibre-retaining grooves are formed in-between a set of fibre locating pins (M) laid side by side. The pins and a base plane (4) on which they are laid are made of hard, rigid material. Guidance for connection and disconnection is provided by guide pins (G1 to G4) of larger diameter which are therefore robust enough to stand up to handling. The guide pins are in direct contact with the locating pins in order to ensure positional accuracy.

Abstract: The light to be injected is supplied by an auxiliary fibre FA which is similar to the receiving fibre FR and which, in contact with the latter and in the same plane of curvature, is subjected to alternating bends. The latter enable the light to leave this auxiliary fibre and to enter the core of the receiving fibre in order to be guided therein. Application to telecommunications.

Abstract: The detection junction is for light passing through a fibre optic esp. multi-mode fibres. The detection area is defined by thinning the 50 micron core (4) and 30 micron thick sheath (2) over a 400 micron length (8, 10). The detector (18) itself is positioned on the parallel section of the fibre adjacent to the neck and is secured to the sheath surface by a transparent glue (22). The detector surface length is between 2 and 10 times the fibre diameter dependent on the insertion loss that can be tolerated. The detector can be used to regulate the light input to the fibre via a feedback loop.

Abstract: In an optical fibre connector, the optical fibre is accurately positioned by clamping it in the channel formed between three parallel rollers each of which bears tangentially on the other two. If the fibre is of exactly the expected diameter such clamping is firm and precise, but given the variation in fibre diameters that must be accommodated there is a danger of there being excessive fibre play. This connector overcomes the problem of fibre tolerances by inserting resilient means in the said channel. Such resilient means may for example be constituted by a set of three resiliently deformable elastomer rings, one mounted on each rod.

Abstract: : Dispositif de mesure multipoint à fibre optique multiplexage temporel. Vingt capteurs de température se succèdent sur une fibre de mesure. Ils réfléchissent chacun successivement une petite fraction de l'énergie d'une impulsion lumineuse d'interrogation parcourant cette fibre, la valeur de cette fraction permettant de connaître la température. Pour cela ils sont constitués chacun par un intervalle entre deux tronçons successifs (F2, F3) d'une fibre optique, cet intervalle étant rempli d'une colle transparente (36) dont l'indice optique varie avec la température. L'impulsion d'interrogation est renvoyée seulement par le dioptre constitué par la face d'extrémité (38) du tronçon amont (F2) de la fibre.
