Holographic contouring and its limitations in nearly specularly reflecting surface measurement

Popis výsledku v původním jazyce

The applicability of the digital holography to grinded surfaces shape measurements is experimentally examined with regard to the surface micro-roughness of brittle materials (optical glass).Multi-wavelength phase shifted digital holographic interferometry (holographic contouring) is used and its performance is analyzed.Holographic contouring is a great candidate for the precise shape measurement technique,which can be applied to the iterative manufacture process of optical elements.Optical surface artifacts with different radii of the spherical (convex and concave) shapes were prepared with different micro-roughness.Their optical surfaces were then holographically recorded using a designed setup.Two different measures were selected to estimate the quality of the holographic recording:first,the intensity profile of the reconstructed surface deviation as a consequence of the micro-roughness decrease,where the shape of the intensity profile develops as the surface is altering from
