Abstract
Proposed are an arrangement and a method for depth-scanning strip triangulation with internal or external depth scan, particularly also for the 3D shape measurement in microscopy and mesoscopy. The robustness of the measurement with wavelet signal generation from an image stack is to be increased. The occurrence of the known and very undesirable 2Pi phase jumps in the phase map is to be avoided as much as possible. To do this, with a measurement instead of a wavelet at least two wavelets with contrast envelope are generated. This is done by a concurrent—then preferably with spectral separation—or by a sequential projection of two strip images with different triangulation wavelengths on the measured object.
