Abstract
An experimental approach is presented to rapidly measure the shape of a micro deep drawing part, which is based on a lensless Fourier-holographic contouring. The surface structure of the investigated object is dominated by the properties of the drawing process. Therefore, the statistical properties of the light scattered from the surface have been investigated and it is shown that digital holography is applicable in this case. Finally, experimental results which prove the big potential of digital holography in regards to inspection of micro parts are given. It is shown that the field of depth can be considerably enhanced by combining several reconstructions associated with different observation planes from a single measurement.
