Pattern method and system for detecting foreign object debris

A method of detecting a non-fixed object in a system during production or manufacturing of the system comprising:

• applying a light emitting or generating substance to a plurality of objects;
• performing a production or manufacturing task with said plurality of objects;
• illuminating said plurality of objects with an object illuminator;
• determining at least one object of said plurality of objects to be a nonmember within at least one known pattern of objects in the system in response to illuminating said plurality of objects;
• and
• identifying said at least one nonmember object to be a non-fixed object.

A foreign object debris detection system comprising:

• a first object illuminator illuminating a plurality of objects having a light emitting or generating substance;
• a first detector generating a first object layout signal in response to illumination of said plurality of objects;
• and
• a controller electrically coupled to said first detector and having a memory storing at least one object pattern, said controller determining an object to be a nonmember of at least one known pattern of objects in response to said first object layout signal.
