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.

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 switch consists of an optical fibre between two plates. The end of the fibre is free to move between two positions (each opposite an external optical fibre). A section of the fibre is fixed. The region between the end and the fixed section is free to bend under the action of a switching force. The fixed section of the fibre is located in a small channel formed by two V-shaped grooves in the opposing faces of the two plates. This channel holds the fibre rigidly. The flexible region is located in a larger channel formed by two larger V-shaped grooves in the plates. The larger channel is large enough to accommodate two fibres side by side. Several such switches can be stacked into an array.

Abstract: The pressure gauge consists of an optical fibre (1) which is enclosed and gripped by two metal ribbons (3) (4). The optical fibre is made of isotropic glass and is weakly birefringent. The metal ribbons are made of steel or steel alloys which are resistant to corrosion and other hostile influences. The birefringence of the optical fibre is such that light vibrating parallel to the direction of any pressure applied is displaced in phase from light which is vibrating in an orthogonal direction. This phase displacement is measured and used to determine the external pressure. The space between the optical fibre and the ribbons may be in vacuum in which case the absolute pressure is measured, or the space may be filled with liquid or gas in which case the difference between the external and internal pressures is measured. ADVANTAGE - Gauge is sensitive and is easy to apply to difficult practical environments.
