摘要： A system (200, 300) and method (400) is disclosed for detecting defects in the surface of a workpiece such as a fiberglass or composite part (100). A light source (201, 305) is positioned to direct light at the workpiece (100) at an oblique angle (401) with respect to the surface of the workpiece (100). At least one camera (205, 303, 304) is positioned to detect light reflected (203) from the workpiece (100) and to generate a light signal corresponding to the reflected light (203). A polarizing lens (204) is positioned between each of the at least one cameras (205, 303, 304) and the workpiece (100). A processor (206) is coupled to each of the at least one cameras (205, 303, 304) to receive the corresponding light signals. The processor (206) is programmed to process the light signals to detect any defects in the surface of the workpiece (100) based on relative magnitudes of the received light signal. A video display (207) and a printer (209, 306) are preferably coupled to the processor (206) to show any detected defects.
