ABSTRACT:
An image station (40) includes multiple light sources (43, 45, 47, 49) emitting lights of different colors to illuminate an object (41) from different directions, thereby forming multiple images of the object (41). Dichroic filters (54, 56, 58) separate lights of different colors from each other. Lights of different colors form images of the object (41) in corresponding cameras (53, 55, 57, 59) simultaneously.
