Abstract

L'invention concerne un dispositif d'analyse optique à point lumineux mobile Il comporte un dispositif qui balaye une ligne d'informations sur un document avec un faisceau lumineux, cette ligne d'informations étant divisée en un certain nombre de segments. Un réseau de lentilles comprenant une lentille associée avec chaque segment projette la lumière réfléchie vers un réseau de détecteurs constitué par un nombre correspondant d'unités de détecteurs orientées suivant un axe perpendiculaire à la direction de balayage. L'invention s'applique notamment aux domaines de la reprographie et de la transmission des fac-similés.
