ABSTRACT:
A method for the non-destructive determination of the stacking order and the fiber orientation of a fiber reinforced composite laminate comprises illuminating optically successively a series of spots of a cross sectional surface of the laminate under examination and detecting light radiated from the respective illuminated spots. An electrical output signal relative to the amount of light detected is provided and a characterization of the laminate indicative of the stacking order and fiber orientation is determined from the electrical output signal. An apparatus is provided for carrying out the method of the present invention.
