| Outline of Final Research Achievements |
In the next-generation manufacturing, in order to improve the shape accuracy of parts to be manufactured, three-dimensional shape measurement at nanoscale is indispensable.
In this research, we systematized the uncertainty estimation theory using error separation and self-calibration. This was applied to the uncertainty analysis of a three-dimensional measuring machine and a semiconductor measuring device, and the effectiveness was confirmed by experimental verification. Furthermore, the uncertainty estimation method was applied to the optical three-dimensional measurement system, and it was experimentally demonstrated that shape measurement can be performed with sub-nanometer uncertainty by self-calibration.
As described above, the uncertainty estimation method has been put to practical use to improve the accuracy of the next generation three-dimensional shape in precision measurement.
