Title: Spectrophotometre a longueurs de trajectoire multiples
Inventor: GARVER THEODORE M
IPC: G01N21/31
Filed: 2001-04-30
Abstract: L'invention concerne un spectromètre ou un procédé de détection d'absorbance de longueurs d'ondes multiples et un appareil fournissant une précision améliorée à un réseau de mesure à différentes longueurs d'ondes. Le spectromètre utilise un système d'éclairage à longueurs d'ondes multiples au moyen d'un réseau de détecteurs indépendants à cellules de longueurs de trajectoire différentes, chaque cellule étant éclairée par une lumière monochromatique prédominante après séparation au moyen d'un élément de dispersion optique. Chaque cellule échantillon possède un longueur de trajectoire optique, des dispositifs optiques et de photodétection qui sont optimisés pour une longueur d'onde spécifique en vue de permettre la mesure précise de l'absorbance à travers une substance prévue.

Title: Identification de canaux dans des reseaux de communication
Inventor: WAN PING WAI
IPC: H04J14/02
Filed: 2002-10-04
Abstract: Dans un réseau optique à multiplexage en longueur d'onde, les canaux sont identifiés par au moins deux tonalités de vibration avec lesquelles le canal est modulé, ces tonalités de vibration alternant selon une périodicité prédéterminée de telle sorte qu'à tout instant, chaque canal est modulé par une seule tonalité de vibration. Les tonalités de vibration son générées en permanence à des fréquences précises. La détection, par détection de tonalités de vibration, de canaux à puissances optiques sur une plage dynamique étendue, fait intervenir un processus par transformées de Fourier rapides permettant de détecter en une seule opération les tonalités de vibration pour des canaux à forte puissance. L'établissement de moyennes cohérentes des résultats des transformées s de Fourier rapide dans le temps permet de détecter des tons de vibration pour des canaux à faible puissance par l'intermédiaire de transformées de Fourier rapides multiples.

Title: Rotary variable optical tap
Inventor: MILLER WILLIAM J
IPC: G02B6/28
Filed: 1991-01-24
Abstract: Method and apparatus wherein continuous indexed lengths of optical fiber are automatically measured for load at failure for each failure below a predetermined maximum stress. A predetermined length of optical fiber is indexed. The optical fiber is clamped at one or more clamp points along its length. Increasing tension is applied to a first indexed length of optical fiber between at least one clamp point and a tension application means.      Increasing tension is applied between an initial value and the predetermined maximum load. The increasing tension is measured during its application. If failure occurs, the actual load at failure is detected while the increasing tension is being applied. When failure does not occur, the first length of optical fiber is released and a second length of optical fiber is indexed to the position where increasing tension is applied to the second length between at least one clamp point and the tension application means.

Title: Device for and method of measurement of an angle of incidence of a luminous beam
Inventor: RHEME CHARLES
IPC: G01S17/46
Filed: 1991-05-22
Abstract: For measuring an angle of incidence of a luminous beam, one employs a polarized luminous beam which is brought to pass through a birefringent plate followed by an analysing polarizer, in order to obtain a succession of fringes of interference, and one analyses by means of an appropriate detector and an electronic circuit the spacings between the crests of said fringes, said spacings being a direct function of the angle to be measured.  One can utilize a measuring device of an angle of incidence for measuring the distance between said device and a reflecting surface of the object to be measured, by determining for a certain position of the object a spacing of reference between the crests of the fringes of interference and by measuring the variations of the spacings as a function of the position of the object, in order to display them in units of length.  With such a method, it is possible to measure the angles of incidence or distances with a device of small dimensions and with a measuring range broader than before and with an increased precision.
