ABSTRACT:
To generate a stereoscopic image of an object (41), two light beams (151, 161) unparallel to each other are used to back light a portion (43) of the object (41). The two light beams (151, 161) are deflected to form two deflected light beams (153, 163) substantially parallel to each other. The deflected light beams (153, 163) form a stereoscopic image of the portion (43) of the object (41). A camera (46) records the stereoscopic image of the object (41). The signal from the camera (46) is processed by a vision computer (48) to reconstruct the stereoscopic image and determine whether the object (41) meets design specifications.
