An intensity compensated scanning system includes laser means (10) for providing a laser beam; scanner means (14) for sweeping the laser beam in an arcuate path across a surface (21) to be scanned; means (22) for sensing the return laser beam reflected from the surface to be scanned; means (38) for quantifying the decrease in the intensity of the return laser beam at the scan extremity portion relative to the intermediate scan portion; and means (30) responsive to the means for quantifying for varying the power to the laser means at the scan extremity portion relative to that at the intermediate scan portion for balancing the intensity of the return laser beam reflected from the surface to the means for sensing.

Ce système de balayage à compensation d'intensité comprend un moyen laser (10) servant à émettre un faisceau laser; un moyen de balayage (14) servant à amener le faisceau laser à balayer selon un trajet courbe une surface (21) à balayer; un moyen (22) servant à détecter le faisceau laser de retour réfléchi par la surface à balayer; un moyen (38) servant à quantifier la diminution de l'intensité du faisceau laser de retour au niveau de la partie d'extrémité de balayage par rapport à la partie de balayage intermédiaire; et un moyen (30) réagissant au moyen quantificateur pour faire varier la puissance du moyen laser au niveau de la partie d'extrémité de balayage par rapport à celle de la partie de balayage intermédiaire, afin d'équilibrer l'intensité du faisceau laser de retour réfléchi par la surface à balayer en direction du moyen détecteur.
