In one embodiment, an apparatus comprises a line scanning camera, a conveyor, an illumination source, and one or more controllers. The conveyor is configured and arranged to move objects past the line scanning camera so that the objects can be imaged thereby. The illumination source is configured and arranged to illuminate the objects for imaging by the line scanning camera. The one or more controllers are configured to cause the line scanning camera to acquire a plurality of individual lines of an image of the object at a rate determined by a speed of the conveyor so that a particular number of lines per unit length of the object are acquired by the line scanning camera, and are further configured to control activation and deactivation of the illumination source so as to synchronize discrete periods during which illumination is provided by the illumination source with line scan periods during which individual lines are acquired by the line scanning camera.
