Title
(EN) APPARATUS FOR POSITIONING AN OPTICAL LINE OF SIGHT WITHIN A HEMISPHERIC REGION
(FR) APPAREIL D'ORIENTATION D'UNE PORTEE OPTIQUE DANS UNE REGION HEMISPHERIQUE
Abstract
(EN)
An optical apparatus for selectively directing a line of sight between a residence location and locations within a substantially hemispherical field of regard. The apparatus includes a stator which supports a first stage for rotation about a first axis of rotation. A second stage is supported by the first stage for at least partial rotation about a second axis of rotation. The first stage and the second stage include respective mirrors which direct the line of sight between the residence location and the locations in the field of regard. The first stage and the second stage are each operatively rotated by one or more foundation-based drive motors or the like. A drive train arrangement is preferably utilized to transfer motive power from the stationary drive motor to the second stage.
(FR)
Un appareil optique est capable d'orienter sélectivement sa portée optique entre une position de départ et différents points d'un champ de perception pratiquement hémisphérique. L'appareil comporte un stator qui supporte un premier étage tournant autour d'un premier axe de rotation. Un second étage est supporté par le premier étage de façon à pouvoir tourner au moins partiellement autour d'un second axe de rotation. Les premier et second étages comportent chacun un miroir qui oriente la portée optique entre la position de départ et d'autres points du champ de perception. La rotation des premier et second étages est assurée par au moins un moteur d'entraînement ou autre situé dans le socle. Un système d'entraînement à engrenages est de préférence utilisé pour transférer la force motrice du moteur d'entraînement fixe au second étage.
