1. A fabrication system comprising:
- a lamination system comprising a layer applicator applying a plurality of composite material layers to a substrate to form a structure; and
a flaw and foreign object debris (FOD) detection system proximate said lamination system comprising;
at least one illumination device illuminating a portion of the structure, said at least one illumination device directing light rays at said portion and at acute angles relative to said portion; and
at least one detector monitoring said portion and detecting FOD in said portion during application of said plurality of composite material layers in response to reflection of said light rays off of said portion.

Abstract
A flaw and foreign object debris (FOD) detection system (11) for use during fabrication of a structure (12) includes an illumination device (13). The illumination device (13) is configured to be in proximity with a fabrication system (10) and illuminates a portion (18) of the structure (12). The illumination device (13) directs light rays (16) at acute angles relative to the portion (18). A detector (14) monitors the portion (18) and detects FOD in the portion (18) during fabrication of the structure (12) in response to the reflection of the light rays (16) off of the portion (18).
