Abstract
A light source is used to illuminate a sawn portion of a piece of wood and exposed surfaces of the saw blade on both sides of the sawn portion. The sawn portion and the exposed surfaces of the saw blade are then imaged substantially concurrently using a single image generator. At least one geometric characteristic of the sawn portion and at least one geometric characteristic of the saw blade are determined based on the imaging.
