Paper Abstract

Grazing incidence interferometry using diffractive elements is a modern laser-optical high precision measuring technique suitable for technical surfaces to measure from deviations of cylinders. Advantages in comparison to tactile measuring techniques consist mainly in a large number of measuring points sampled at the entire cylinder jacket area with high radial resolution in a very short time so that an improved reliability of the measurement, which represents the real surface of the workpiece under test, is achieved. This contribution gives a short introduction to the principle of interferometric cylinder form testing. An own set-up is presented as well as a stationary measuring system, working both according to the transmission method. As a modification of this, a mobile sensor, which is able to measure bores accessible only on one side, is introduced. The potential of grazing incidence interferometry is demonstrated by means of comparative measurements with conventional tactile measuring methods.
