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.
