Abstract:
An apparatus for measuring geometric deviations in a doctor blade includes a camera defining an optical axis. The optical axis defines an X-axis in a Cartesian coordinate system. An origin of the Cartesian coordinate system defines an intersection point. A first light source has a first central axis. The first central axis is angularly disposed from the X-axis by a first angle with respect to the X-axis. A second light source has a second central axis. The second central axis is angularly disposed from the X-axis by a second angle with respect to the X-axis. A doctor blade holding device is configured to mount a doctor blade wherein a portion of the doctor blade to be measured is positioned at the intersection point.
