Abstract

Selon des modes de réalisation décrits ci-inclus la présente invention concerne d'une manière générale un dispositif qui surveille la présence d'objets passant à travers ou frappant une coque virtuelle près du dispositif, désignée ci-inclus par rideau de lumière, qui est créée en faisant tourner rapidement un capteur de ligne et un laser en ligne de manière synchrone. Les limites du rideau de lumière sont définies par une ligne de balayage définie par l'intersection des plans de détection et d'éclairage.
