B8.3 - Multifunctional, Laserinterferometric Measurement Systems

Walter Schott, Wolfgang Poeschel & Denys Dontsov
The trend in many fields of enabling technologies, such as microelectronics, communications, microsystems, and micromechanics, toward imposing increasingly stringent demands upon precision continues. Those types of technologies allow creating micromechanical components having dimensions of a few micrometers that have to be accurately measured, positioned relative to one another, and assembled. In that conjunction, laser-interferometric metrology provides unique opportunities that combine measurements over large ranges at extraordinarily fine resolutions with traceability of measurement results to international...
