Many manufacturers of microsystems have pushed test and measurement processes to the forefront of their ``needs-attention`` list. Wanted are measurement and inspection techniques that are very fast, robust, and relatively low cost compared to the products being investigated. The reason for this effort is obvious: Properties determined on much larger specimens cannot be scaled down from the bulk material without any experimental verification. Further on, in microscale the materials behavior is noticeably affected by the production technology. Therefor e simple and robust methods to analyze the shape and deformation of the microcomponents are needed. Together with the knowledge of the applied load and appropriate physical models these data can be used for the derivation of material parameters such as the Young`s modulus, the Poisson ratio and the thermal expansion coefficient.
