| 摘要 | An apparatus for inspecting an article includes a laser assembly which is operable to direct a laser beam against a series of locations disposed along a line which extends across discontinuities in a surface of the article. The position of at least of one location against which the laser beam is directed is detected. The at least one location is spaced from discontinuities in the surface of the article. | ||

| 主权项 | 1. A method of inspecting a ceramic core having an airfoil portion in which discontinuities are formed, said method comprising the steps of positioning the core in a fixture, directing a laser beam against a series of locations disposed along a line which extends across discontinuities in a major side surface of the airfoil portion of the core, and detecting the position of at least one location against which the laser beam is directed, the at least one location being spaced from discontinuities in the major side surface of the airfoil portion of the core. | ||
