Inspection method of perforation hole structure of component

摘要

Until recently inspection method of the perforation hole of the component by technology the clogging by the thermo- graph generally uses the hot gas for detection. According to the inspection method of perforation hole structure of the component (10) due to this invention, as for this, the medium which at least possesses one absorption end in the wave length range of the camera (13) is used, this medium is simplified at opacity by it tries to appearing in the camera picture (13).
