Abstract
A multispectral imaging system and method and a system for composite layup are provided in order to detect foreign object debris during the fabrication of a composite structure. In the context of a method, a surface of a composite material is illuminated with near infrared light. The method also detects the near infrared light following interaction of the near infrared light with the composite material. Following detection, the method analyzes a spectrum of the near infrared light to detect foreign object debris upon the composite material. The method analyzes the spectrum of near infrared light by distinguishing between different types of foreign object debris as a result of comparing the spectrum of near infrared light to predefined spectral signatures of a plurality of different types of foreign object debris. The method may also determine the size and location of the foreign object debris.
