Abstract

L'invention concerne la formation d'image par un dispositif de balayage du type à caméra utilisant un plan de formation d'image partiel, comprenant un socle, un module de photographie numérique, un bras pliant, un arbre et une colonne de support montée sur le socle, le module de photographie numérique étant monté sur le bras pliant et le bras pliant étant monté sur la colonne de support par l'intermédiaire de l'arbre ; le module de photographie numérique comprend une puce de commande de capteur, un capteur et un objectif de détection, la puce de commande de capteur commandant le capteur et s'y connectant, et le capteur étant placé sur une partie du plan de formation d'image de l'objectif de détection. Conformément à la présente invention, le capteur du module de photographie numérique est placé sur une partie du plan de formation d'image de l'objectif de détection afin de présenter une image complète de manière à ce que la position du capteur puisse être ajustée selon les nécessités. Une image nette peut ainsi être obtenue en installant le module de photographie numérique directement sur l'extrémité avant de la colonne de support, l'extension du bras pliant étant fortement réduite ou sans extension du bras pliant, et une image complète pouvant être obtenue en utilisant directement le plan de formation d'image partiel de l'objectif.
