SYSTEM AND METHOD FOR HIGH SPEED FOD DETECTION
First Claim
1. A system for detection of foreign object debris material, the system comprising:
- an ultraviolet light source configured to direct ultraviolet light across a surface, wherein the surface is an outer surface of a composite part being formed by a composite layup machine;
an ultraviolet light camera configured to scan the surface and output a first signal proportional to reflected ultraviolet light reflected by at least one of the surface and a first type of foreign object debris material, the reflected ultraviolet light responsive to the ultraviolet light from the ultraviolet light source; and
a controller coupled to the ultraviolet light source and to the ultraviolet light camera, the controller configured to compare the first signal from the ultraviolet light camera with a first threshold to detect presence of the first type of foreign object debris material.

Abstract
A system for the detection of foreign object debris material on a surface includes an ultraviolet light source configured to direct ultraviolet light across a surface. The surface is an outer surface of a composite part being formed by a composite layup machine. The system includes an ultraviolet light camera configured to scan the surface and output a first signal proportional to reflected ultraviolet light reflected by at least one of the surface and a first type of foreign object debris material. The reflected ultraviolet light is responsive to the ultraviolet light from the ultraviolet light source. The system also includes a controller coupled to the ultraviolet light source and to the ultraviolet light camera. The controller is configured to compare the first signal from the ultraviolet light camera with a first threshold to detect presence of the first type of foreign object debris material.

19. A method for detection of foreign object debris material on a surface, the method comprising:
-
receiving a signal at a controller from an ultraviolet camera, the signal proportional to ultraviolet light reflected from the surface, ultraviolet light reflected by a first type of foreign object debris material, or both, wherein the ultraviolet camera scans the surface responsive to ultraviolet light directed across the surface from an ultraviolet light source; comparing, at the controller, the signal to a threshold to detect presence of the first type of foreign object debris material; and in response to detection of the presence of the first type of foreign object debris material, sending a first command from the controller to a controllable nozzle, wherein the first command causes the controllable nozzle to direct high pressure gas at the first type of foreign object debris material. - View Dependent Claims (20)
