Abstract

The measurement of displacement of surfaces due to dynamic vibrating is very difficult, because of the high commutator velocity and the small translation. With the aid of the described procedure it is possible to detect surface displacement by non-contact gauging. It works on the principle of the diffraction of light in a slit. The theoretical foundations are explained and suitability for detecting surface displacement is shown by the example of a rotating engine commutator.
