Claim:
1. An imaging system comprising: a camera with a two dimensional full-frame electronic sensor: an objective lens component configured to project an image of at least a two-dimensional portion of a substrate onto the two dimensional full-frame electronic sensor of the camera to produce a two-dimensional image: a positioning stage configured to move in continuous motion the substrate in a first known lateral direction with respect to the objective lens component while the camera with the two dimensional full-frame electronic sensor produces the two-dimensional image: a scan mirror configured to tilt relative to a viewing axis between the two dimensional full-frame electronic sensor and the substrate in continuous motion in coordination with the moving positioning stage, while the positioning stage moves the substrate in the first known lateral direction, in order to reflect light from the objective lens component to the camera while maintaining the substrate image stable at the electronic sensor: a first tilt plate positioned in an optical path between the scan mirror and the camera, wherein the first tilt plate is configured to cause first offset corrections to the substrate image that is acquired by the objective lens component; and a second tilt plate positioned in the optical path between the scan mirror and the camera, wherein the second tilt plate is configured to cause second offset corrections, in the substrate image in a second direction that is perpendicular to the first offset corrections.
