CALIBRATION USING CYLINDRICAL ARTIFACTS FOR LASER 3D MEASUREMENT SYSTEM

Kazuhiro Enami
Abstract:
We are now developing inner shape measurement system for superconducting accelerator cavities. An acceleration cavity is shaped like bellows which have some cells. Inner shape of a cavity influences accelerating efficiency of particles. To improve and inspect accelerator cavities, we are now developing a system which can measure inner 3D shape. This system scan inner surface by inserting and rotating a laser displacement sensor unit attached to the end of the pole. This system is simple and useful not only for an accelerator cavity but also for a long pipe and a deep hole on an industrial part. We proposed calibration method for such a system. We simulated and analyzed the proposed calibration method and shows availability of cylindrical artifact calibration method.
