Abstract

For surface topography measurement and characterization it is necessary to calibrate the measuring devices. For comparison of measurements using different techniques it is important to specify the spatial frequency range of the microstructure. Two new methods for the measurements of surface shape and microstructure will be described; namely a confocal technique based on microlens arrays and an interferometrical technique based on heterodyne interferometry.
