Abstract
A method and an apparatus for inspecting parts for surface contamination including the steps of covering the part with a film of water, and then scanning the wetted part with a infrared camera to preserve the reflected image of the reflected infrared light thereby defining a water break area of contamination.
Claims8
A method of inspecting the surface of a part for surface contamination comprising the steps of:
- dipping the part in a water rinse tank;
- exposing the part to a 7–14 μm wave length infrared camera to preserve an image of infrared emitted energy;
- and
- defining a water break area of contamination using said image.

An apparatus for inspecting a part for surface contamination comprising:
- a water rinse tank for dipping said part;
- and,
- an infrared camera for scanning a source of infrared energy distribution from the part and defining a water break area of contamination on the part.
A method of inspecting the surface of a metal part for surface contamination comprising the steps of:
- covering the metal part with a film of water;
- scanning the part with an infrared camera;
- using said camera to receive an image generated from emitted infrared energy;
- and
- defining a water break area of contamination on said part using said image.
