Abstract: An imaging system for detecting a defect on a workpiece surface includes one or more independently operating imaging modules and a control system including one or more processors having non-transitory computer-readable instructions for receiving and processing digital data of images captured by the one or more imaging modules to provide a combined image of a portion of the workpiece surface. The independently operating imaging modules each include a lighting unit having an adjustable support frame carrying a plurality of indexing light sources and an imaging unit including one or more imagers carried by the support frame. The imaging unit includes a pair of imagers disposed on the adjustable support frame to capture one or more images of a portion of the workpiece surface. Imaging modules for use in the imaging system, and methods for scanning a portion of a workpiece by the imaging system are described.
