Abstract
An optical apparatus and method for simultaneously scanning the profile of at least two adjacent surfaces of an article such as a wooden board moving along a travel path axis passing through an inspection area located at a central plane transverse to the travel path axis, involve first and second scanning zones sufficiently spaced one with another along the travel path axis to substantially prevent mutual scanning interference between the profile sensors used, while providing a compact arrangement of profile sensors. For so doing, one the first sensing field and the first laser beam of the first profile sensor is crossing the central plane toward the other one of the first sensing field and the first laser beam, and one the second sensing field and the second laser beam of the second profile sensor is crossing the central plane toward the other one of the second sensing field and the second laser beam.
