Abstract:
1. An optical scanning apparatus for scanning a surface of an object comprising: a conveyor for transporting an object into a scanning zone; an image sensor having a sensor plane and an image data output; an optics system defining an optical path having an axis and a first end whereat the object surface is locatable in the scanning zone for scanning and a second end at said sensor plane; an object position sensor that provides skew information of an object traveling on the conveyor; and at least one linear actuator operatively coupled to the image sensor to pivot the image sensor plane along a vertical image axis and a horizontal image axis to control the orientation of the image sensor plane relative to the optical path axis such that when an object surface is located at the first end of the optical path at an orientation skewed from a plane orthogonal with the optical path axis at said first path end, the at least one linear actuator orients the sensor plane to a corresponding skewed orientation relative to a plane orthogonal with the optical path axis at said second path end.
