Abstract:
1. An automated optical inspection system, comprising: a pulsed light source illuminating an article to be inspected thereby; at least one camera having a field of view configured to capture at least one image of a portion of the article in the field of view; and a relative motion provider operative to provide relative motion between said at least one camera and the portion of the article in the field of view, wherein, said relative motion provider includes a continuous motion provider which provides a continuous motion at a constant velocity relative to the camera and a periodic motion provider on the constant motion provider which provides a variable velocity over time relative to the camera, said relative motion is a superposition of a continuous component of motion provided by the continuous motion provider and a periodic component of motion provided by the periodic motion provider which lessens the velocity of the article relative to the camera during imaging.
