APPARATUS AND METHODS FOR CHARACTERIZING LENSES
A test chart for characterizing lenses comprises X radial lines extending from a central point and Y concentric X-sided polygons centered at the central point. Each of the X radial lines intersects one vertex of each of the polygons. Each of the X radial lines is divided into Y segments by its inter...

| Zusammenfassung: | A test chart for characterizing lenses comprises X radial lines extending from a central point and Y concentric X-sided polygons centered at the central point. Each of the X radial lines intersects one vertex of each of the polygons. Each of the X radial lines is divided into Y segments by its intersection points with the central point and with the polygons. The radial lines and the polygons define boundaries of X*Y non-overlapping patches. At least two of the patches share a boundary and are distinctly colored from each other. |
