Optical sensors are very suitable for the analysis of microscopic structures and micro devices. We compare two very promising methods: the white-light interferometry and the fringe projection technique for the application to this task. The fringe pro

Summary The inspection of an engine cylinder wall is an important industrial application for optical sensors. This task is an example, where a 3-D characterization of the microstructure is needed to obtain a full functional surface description. Recen

Summary We are presenting a new depth-scanning fringe projection technique (DSFP) on the basis of triangulation for the absolute 3-D measurement of a macroscopic scene. The absolute phase can be determined for any desired depth range of the measureme

Optical sensors are designed usually for microscopic or for macroscopic applications. White-light interferometry on the other hand enables high-resolution measurements to be made for small and for large fields. In this paper we present a flexible set

Coherence scanning interferometry is a useful instrument for measuring the geometry of a wide range of surfaces with high resolution. By introducing two objectives with a high numerical aperture in both arms of a Michelson interferometer it is possib
