1. An inspection system comprising:

  • an idler wheel coupled to a fabrication system and contacting a backing layer of an applied material;

    a rotation sensor configured to monitor the idler wheel and to generate a rotational signal;

    an illumination device configured to illuminate a portion of a composite structure to produce an illumination;

    a detector configured to detect at least one flaw and FOD (foreign objects and debris) based on the illumination, the detector further configured to generate a flaw and FOD detection signal; and

    a controller coupled to said rotation sensor and configured to determine at least one characteristic of the at least one flaw and FOD on the composite structure in response to said rotation signal and the flaw and FOD detection signal.
