DEFORMATION LOGGING APPARATUS AND METHOD

摘要

A method and apparatus for inspecting the internal configuration of a circular opening wherein a scanning probe device having a feeler arm is extended into the opening and the arm is pivoted into engagement with the inner wall of the opening. The feeler arm pivots about its pivoting axis while the pivoting axis is revolved about an axis of revolution within the opening. The degree of variation between the angle of the feeler arm and the axis of revolution indicates the internal contour of the opening.
