Abstract
A method for measuring geometric deviations of a doctor blade using an apparatus, including initializing the apparatus, mounting the doctor blade to a doctor blade holding device, illuminating the doctor blade with light, positioning a first portion of the doctor blade at an optical axis of a camera, obtaining a first image signal from the camera that corresponds to the first portion of the doctor blade, generating a first doctor blade geometry value associated with the first image signal, and determining if a first geometric deviation of the doctor blade is within acceptable tolerance using the first doctor blade geometry value.
