Abstract

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.
