ABSTRACT:
The invention provides methods and apparatus for machine vision illumination by moving a non-diffuse light beam over selected points on the object so that each is illuminated at substantially the same angle by multiple rays during acquisition of an image frame. An apparatus for illuminating an object to facilitate its being imaged by an image acquisition device, e.g., a camera, includes a radiation source that generates and transmits to a region of the a non-diffuse beam of imaging radiation having a non-point cross-section. A dithering element moves the beam so that at least a region of the object is illuminated at substantially the same angle by multiple rays during an image acquisition period.
