| 摘要 |
The invention provides a system for measuring, characterizing, verifying and position-determining material properties of a selected object to be measured, in particular thickness distribution. A mobile measuring unit which is manouvered and operated manually or with the aid of a remote-control transport device senses half-wave resonance in objects to be measured and computes the thickness distribution. A new, accurate, partly acoustic positioning system determines the position of the measured area. |
