Title
(EN) HIGH SPEED IMAGING APPARATUS FOR CCD BASED SCANNERS
(FR) DISPOSITIF D'IMAGERIE A GRANDE VITESSE CONÇU POUR LES SYSTEMES D'EXPLORATION A COUPLAGE DE CHARGE
Abstract
(EN)
A high speed imaging apparatus for CCD based scanners comprises a housing having separate compartments which complement modular assemblies installed therein. A decoder compartment houses components associated with locating and decoding an image. An optics compartment houses the mirrors and associated optics for reflecting the subject image onto the CCD detector. A lighting compartment includes high intensity lamps and the associated components for illuminating an object to be imaged. The lighting compartment includes a heat management system which removes the heat from the high intensity lamps and prevents heat from migrating to other compartments within the housing.

Un dispositif d'imagerie à grande vitesse, conçu pour les systèmes d'exploration à couplage de charge, comporte un habitacle doté de compartiments séparés qui sont complémentaires des assemblages modulaires installés à l'intérieur de ces systèmes. Un compartiment destiné au décodage renferme des composants utilisés pour localiser et décoder une image. Un compartiment optique renferme les miroirs et les dispositifs optiques associés permettant de réfléchir l'image sujet sur le détecteur à couplage de charge. Un compartiment destiné à l'éclairage comporte des lampes à haute intensité et les composants associés permettant d'éclairer un objet dont on veut obtenir une image. Ledit compartiment destiné à l'éclairage comporte un système de régulation thermique qui dissipe la chaleur provenant des lampes à haute intensité et empêche la migration de cette chaleur vers d'autres compartiments de l'habitacle.
