摘要： PROBLEM TO BE SOLVED: To provide an inspection apparatus which takes advantage of the characteristics of each of an eddy current testing (ECT)-based flaw detection apparatus and an imaging-based flaw detection apparatus in an inspection system for detecting flaws on a metal bar. SOLUTION: The ECT-based flaw detection apparatus 20 and the imaging-based flaw detection apparatus 30 are disposed along a movement path in a predetermined positional relationship with each other, for example, keeping a predetermined fixed offset distance between them. A synchronization mechanism 46 synchronizes output data series from the two flaw detection apparatuses based on the predetermined relationship so as to align the data series depending on an axial position on the metal bar 11. A processing unit 40 is configured to process the synchronized data series for the detection of flaws, and the information on these flaws is also synchronized (axial direction). The synchronization permits a variety of cross-referencing operations, such as flaw verification on the presence of flaws 14 and augmenting imaging-based flaws with flaw depth information from the ECT-based apparatus.

摘要： An inspection system is used to view an image of the inside diameter (ID) of an engine bearing. The inspection system includes a stationary line scan camera, a pivoting mirror, a scanning mirror and a stationary mount. The engine bearing is placed in the stationary mount such that the bearing remains motionless throughout the entire scanning process. The light line generator produces a light line that initially contacts a beam splitter. The beam splitter then guides the light line onto the pivoting mirror, which then directs the light line onto one of a pair of stationary mirrors and then finally onto the scanning mirror. The scanning mirror will swepp the light line across a portion of hte engine bearing ID surface. The light line will generate refected images of the ID surface. These reflected images will return along the light line's path; however, instead of being directed back into thelightl ine generator by the beam splitter, the reflected images will pass through the beam splitter. Once the reflected images pass through the beam splitter. Once the reflected images pass through the beam splitter, they will journey through the lens and into the stationary line scan camera. From the stationary line camera, the reflected images can be viewed on monitor and recorded for future use.

摘要： A method is used for imaging applications so that one can simultaneously apply multiple illumination schemes and simultaneously acquire the images, each associated with one of the multiple illumination schemes. The illumination schemes can be, but not limited to, any combination of reflective illumination, transmitive illumination (backlighting), bright field illumination, dark field illumination, diffused illumination, cloudy-day illumination, and structured illumination. The radiation can be in any wavelengths, ranging from sonic waves, ultra sound, radio waves, microwaves, infrared, near infrared, visible light, ultra violet, X-rays, and gamma rays. The radiation of each of the illumination schemes used in an imaging application is modulated, that is, affixed with a unique signature. One or more imaging devices can be used to collect the radiating rays simultaneously after the rays interact with the object(s). The image signal(s) are then demodulated, separated into several images, each is associated with an illumination scheme, based on the signatures. A preferred embodiment is to use radiation wavelengths of 430 nm, 575 nm or 670 nm as the signatures.

The inspection system includes a stationary line scan camera, a pivoting mirror, a scanning mirror and a stationary mount. The engine bearing is placed in the stationary mount such that the bearing remains motionless throughout the entire scanning process. The light line generator produces a light line that initially contacts a beam splitter.

The scanning mirror will sweep the light line across a portion of the engine bearing ID surface. The light line will generate reflected images of the ID surface.
