Title
(EN) CALIBRATION SYSTEM FOR A PHOTOMULTIPLIER TUBE
(FR) SYSTEME D'ETALONNAGE POUR UN TUBE DE PHOTOMULTIPLICATEUR
Abstract
(EN) Optical systems are provided. In one embodiment, the optical system includes a detector for detecting a light signal. A light signal gatherer and guider is optically connected with the detector for gathering the light signal and guiding the light signal to the detector. The light signal gatherer and guider has a check signal entrance location disposed along an outer surface of the light signal gatherer and guider. A check signal source is optically connected with the light signal gatherer and guider so that a check signal generated by the ckeck signal source randomly illuminates the check signal entrance location on the outer surface of the light signal gatherer and guider.
(FR) Cette invention concerne des systèmes optiques. Dans une forme de réalisation le système optique comprend un détecteur servant à détecter un signal lumineux. Un dispositif de collecte et de guidage des signaux lumineux est optiquement connecté au détecteur pour collecter les signaux lumineux et les guider jusqu'au détecteur. Le dispositif de collecte et de guidage des signaux lumineux comporte un point d'entrée des signaux de contrôle situé sur une surface externe du dispositif de collecte et de guidage des signaux lumineux. Une source de signaux de contrôle est optiquement connectée au dispositif de collecte et de guidage des signaux lumineux, ceci permettant à un signal de contrôle généré par la source de signaux de contrôle d'éclairer de manière aléatoire le point d'entrée des signaux de contrôle situé sur la surface externe du dispositif de collecte et de guidage des signaux lumineux.
