Abstract

L'APPAREIL COMPREND UNE SOURCE D'ENERGIE ELECTROMAGNETIQUE OU RAYONNANTE 40, DES MOYENS 50 DE CAPTATION ET DE GUIDAGE DE L'ENERGIE ET DES MOYENS DE SUPPORT 60 COMPRENANT DES MOYENS 60A FORMANT MASQUE POUR LE FILM DE FORMATION D'IMAGES. L'APPAREIL EST NOTAMMENT APPROPRIE POUR LA FORMATION, A L'AIDE D'UNE LAMPE ECLAIR, D'UNE IMAGE SUR UNE MICROCARTE OU UNE MICROFICHE ET PERMET A UNE SOURCE D'ENERGIE DE FORMATION D'IMAGES TELLE QUE, PAR EXEMPLE, UN TUBE ECLAIR AU XENON D'ETRE EXCITEE A DES NIVEAUX D'ENERGIE INFERIEURS ET PENDANT DES DUREES PLUS COURTES TOUT EN OBTENANT UNE UNIFORMITE DE LA DISTRIBUTION D'ENERGIE SUR UNE ZONE RELATIVEMENT LARGE AU NIVEAU DU PLAN DU FILM.THE APPARATUS INCLUDES AN ELECTROMAGNETIC OR RADIANT ENERGY SOURCE 40, MEANS 50 FOR CAPTURING AND GUIDING ENERGY AND SUPPORT MEANS 60 INCLUDING MASK-FORMING MEANS 60A FOR THE IMAGE FORMING FILM. THE APPARATUS IS ESPECIALLY SUITABLE FOR TRAINING, USING A LAMP, AN IMAGE ON A MICROCARD OR A MICROSHEET AND ALLOWS A SOURCE OF ENERGY TO FORM IMAGES SUCH AS, FOR EXAMPLE, A XENON LIGHTNING TUBE TO BE EXCITED AT LOWER ENERGY LEVELS AND FOR SHORTER DURATIONS WHILE OBTAINING A UNIFORMITY OF ENERGY DISTRIBUTION OVER A RELATIVELY LARGE AREA AT THE LEVEL OF THE FILM PLAN.
