Title (EN) METHOD AND SYSTEM FOR MEASURING THE CURVATURE OF AN OPTICAL SURFACE
(FR) PROCEDE ET SYSTEME POUR MESURER LA COURBURE D'UNE SURFACE OPTIQUE
Abstract:
(EN) A system and method of measuring the curvature of a surface of a object operate by illuminating the object surface with a light pattern having a known size to produce a virtual reflected image from the object surface; measuring a size of the virtual reflected image produced by the object surface from the light pattern; and calculating a curvature of the object surface from the known size of the light pattern and the size of the virtual reflected image.
(FR) L'invention concerne un système et un procédé servant à mesurer la courbure d'une surface d'un objet. Selon l'invention, on éclaire la surface de l'objet au moyen d'un motif lumineux de taille connue afin de produire une image réfléchie virtuelle à partir de la surface de l'objet, on mesure une taille de l'image réfléchie virtuelle produite par la surface de l'objet à partir du motif lumineux et on calcule une courbure de la surface de l'objet à partir de la taille connue du motif lumineux et de la taille de l'image réfléchie virtuelle.
