Jean Pierre Chambard, Vincent Chalvidan: Method and device for measuring at least a geometric quantity of an optically reflecting surface. Gibbons Del Deo Dolan Griffinger & Vecchione, December 9, 2004: US20040246497-A1

This invention concerns a process and a device for measuring at least one geometric magnitude of an optically reflective surface. The process is rapid, reliable, and precise, and makes it possible to quantify the curvatures and/or slopes and reliefs of the optically reflective surface without the ri ...
