Title
(EN) SCAN MIRROR REMOTE TEMPERATURE SENSING SYSTEM AND METHOD
(FR) PROCEDE ET SYSTEME DE TELEDETECTION DE CHALEUR POUR MIROIR DE BALAYAGE
Abstract
(EN)
A remote temperature sensing system (10) for a scanning mirror (7). The system (10) includes a sensor which detects heat radiated by the mirror and provides a signal in response thereto. In the illustrative implementation, the system (10) includes a thermistor mounted within a housing. The housing is contoured to maximize the receipt of thermal energy thereby. A mounting assembly maintains the thermistor a predetermined nonzero distance from the scanning mirror (7). The invention includes a shroud (12) mounted on the mirror (7) for shielding the thermistor and a support tube connected to the thermistor housing on a first end and to a base on the second end thereof. The support tube is adapted to remain stationary within the shroud as the scanning mirror and the shroud rotate due to the scanning of the mirror. Wires are connected to the thermistor on a first end thereof and are wrapped around the support tube. The wires include a length of electrically conductive material having a resistivity which has a low sensitivity to temperature variations. The sensor output is processed in a conventional manner to provide an output indicative of the temperature of the mirror.
(FR)
La présente invention à trait à un système de télédétection de chaleur (10) pour un miroir de balayage (7). Le système (10) comprend un détecteur qui détecte d'abord la chaleur de rayonnement réfléchie par le miroir puis émet un signal. Dans un mode de réalisation d'illustration, le système (10) comprend un thermistor monté à l'intérieur d'un logement. Ce logement est conçu avec un profil destiné à permettre une réception maximale d'énergie thermique. Une plaque de fixation maintient le thermistor à une distance prédéterminée différente de zéro du miroir à balayage (7). L'invention comprend une enveloppe (12) montée sur le miroir (7) pour protéger le thermistor, et un tube-support raccordé au logement du thermistor au niveau d'une première extrémité et à une base au niveau de la seconde extrémité. Le tube-support est conçu pour demeurer fixe à l'intérieur de l'enveloppe lorsque le miroir de balayage et l'enveloppe tournent sous l'effet du balayage du miroir. Des fils reliés au thermistor à une première extrémité s'enroulent autour du tube-support. Ces fils comprennent un segment d'un matériau électriquement conductif caractérisé par une résistivité faiblement sensible aux variations de température. Le signal du détecteur est traité d'une manière classique pour fournir un signal indicateur de la température du miroir.
