Abstract:
A method for positioning an end of a probe on a target surface inside an open cavity in a test object, comprising the steps of fixing the test object in a given position; adjusting an optical instrument in such a manner that the target surface is located essentially on its optical axis and the position of the target surface in the longitudinal direction of the optical axis is defined; attaching the probe on a pivotable arm, which is supported by a stand; causing the pivotable arm to perform a pivotal movement about a pivot point located at a distance from the optical axis, such that the end of the probe is positioned essentially on the optical axis a certain distance into the open cavity; and thereafter moving the pivotable arm in parallel with the optical axis, such that the end of the probe reaches the target-surface position defined with the aid of the optical instrument.
