Kinematic analysis of 3-dimensional system for NDE (nondestructive examination)

Abstract

The 3-dimensional measuring machine using an ultrasonic sensor is used for NDE (nondestructive examination). It is applied to the inspection of pipelines, boreholes, pressure vessel and tank, and so on, in particular, when a harsh environment prohibits the use of moving mechanical parts. The 3-dimensional measuring machine using an ultrasonic sensor, which measures 1-dimensional information and 2-dimensional information simultaneously from a target of inspection, and then reconstruct 3-dimensional information. So we can find the situation in progress and predict remaining life and corrosion without destructive examination. The 3-dimensional measuring machine is portable.
