Title
(EN) SHUTTER FOR RADIATION SOURCE OF EXTENDED AREA
(FR) OBTURATEUR POUR SOURCE DE RADIATION D'UNE ZONE ETENDUE
Abstract
(EN)
Shutter (30) produces a pulsed emission from a beacon. Hot plate (40) radiates upward through openings (67). Shutter plate (52) slides to open and close the view of the hot plate. Outer optical plate (38) has divergent and adjoining reflector openings (67) so that a large area source is seen when the shutter is open.
(FR)
Un obturateur (30) produit une émission pulsée à partir d'une balise. Une plaque de chauffage (40) irradie vers le haut au travers d'ouvertures (67). Une plaque d'obturateur (52) coulisse pour ouvrir et fermer la visée de la plaque de chaleur. Une plaque optique extérieure (38) possède des ouvertures réflectrices divergentes et adjointes (67) de sorte que l'on voit une grande source de zone lorsque l'obturateur est ouvert.
