Abstract

TITRE : Dispositif et procédé pour déterminer l’état de la surface d’une chaussée de circulation Dispositif (100) pour déterminer l’état de la surface d’une chaussée de circulation (101), comprenant une source lumineuse (102) émettant une lumière primaire (103) en direction de la chaussée de circulation (101), et un dispositif détecteur (104) pour saisir la lumière secondaire (105) réfléchie et/ou diffusée par la chaussée de circulation (101), et une unité d’exploitation (107) pour déterminer à partir de la lumière secondaire (105) saisie, l’état de surface de la chaussée de circulation (101). Le dispositif (100) comporte au moins une première puce semi-conductrice (108-1) munie d’au moins deux diodes (102-1 à 102-4, 104-1 à 104-4). Figure 1
