Typical applications are pattern generation for deepUV-laser mask writing or structured illumination in microscopy. Development and optimization of such SLMs requires detailed knowledge of the device behaviour under operating conditions. Here, the flatness of each single mirror effects the image resolution and contrast of the generated pattern and is amongst others a characteristic property of SLMs. In this context a surface topography measurement under laser exposure (in situ) was designed. The interferometric setup uses the phase-shift principle and allows a resolution in z-direction in the single-digit nanometer range. During irradiation with UV-laser light at 248 nm (KrF) and energy densities of up to 20 mJ/cm2 the change in single micro-mirrors topography was detected in situ. Measurementswith varying pulse energies were carried out to identify an impacton the device performance. In general, the setup is neither limited to a specific illumination wavelength nor to micro-mirrors as structures under test.}, language = {en} } @techreport{MuellerDieterBauhusetal., author = {M{\"u}ller, J{\"o}rg and Dieter, M. and Bauhus, J. and Spellmann, H. and M{\"o}hring, B. and Wagner, S. and Wolf, Heino and Niekisch, M. and Weiger, H. and Feindt, Peter H. and Hamm, Ulrich and W{\"a}tzold, Frank and Wolters, Volkmar and Engels, Eve-Marie and Schraml, U. and Lang, F. and Pr{\"o}bstl-Haider, U. and Richter, K.}, title = {Wege zu einem effizienten Waldnaturschutz in Deutschland.
