Method And Apparatus For Measuring The Optical Quality Of A Reflective Surface
US Patent:
2003005, Mar 20, 2003
Filed:
Sep 20, 2002
Appl. No.:
10/251378
Inventors:
Alex Redner - Plymouth Meeting PA, US
International Classification:
G01N021/55
US Classification:
356/448000
Abstract:
A method and apparatus for inspecting the optical quality of a reflective surface providing for the reflecting of a beam of light off the reflective surface, measuring an intensity of the reflected light at a first distance from said reflective surface, measuring an intensity of the reflected light at a second distance from said reflective surface, and comparing the intensity of the light measured at the two distances to determine the distortion of the reflective surface.
