IN-PROCESS VISION DETECTION OF FLAWS AND FOD BY BACK FIELD ILLUMINATION
First Claim
1. A method of detecting a flaw or a FOD in a structure during fabrication of that structure comprising:
- generating light rays;
directing said light rays at a portion of the structure and at acute angles relative to said portion;
monitoring said portion; and
detecting FOD in said portion during fabrication of the structure 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).
