  23. Most white-light interferometers employ the Michelson design. Light from a white source (with a coherence length of typically a few micrometres) is passed through a half-silvered mirror (beam splitter). The two resulting beams illuminate simultaneously the object for measurement and a reference mirror Explanations White-Light-Interferometry Light waves reflected by the object and the reference mirror pass through the beam splitter again and on a detector (camera chip). If the path length to the object matches the path length to the reference mirror, the instrument produces interference patterns that are sensed by the camera and can be analysed. Software interprets fluctuations in brightness in order to compute the object distance for each object point. As the object moves along the optical axis, a height map of the object with sub-micrometre precision can be created in this way. The scanning speed is typically between a few micrometres per second and 500 µm/s, depending on the precision required.

  24. Explanations Measuring Principle

  25. Explanations Deflectometry Local variations of the surface’s gradient cause deformations of the reflected fringe pattern. Thus, compared to other optical 3D sensors, deflectometry does not measure the local height of a surface but the local gradient. The shape of the surface can be calculated by integration of the measured slope data. Sinusoidal fringes are projected on a screen and observed by a camera using the specular surface under test as a mirror. As we cannot focus onto the surface and the reflected pattern at the same time, sinusoidal fringes are optimal for deflectometry – the phase does not change even if the fringes are blurred.
