Fast white-light interferometry with Hilbert transform evaluation
Original language description
White-light interferometry is an established method for the measurement of the shape of objects. Unlike to the classical interferometry, white-light interferometry can measure the shape of objects with rough surface. A major disadvantage of white-light interferometry is the low scanning speed and thus the long measurement time. This disadvantage can be overcome by a strong undersampling and Hilbert transform evaluation. We propose a system that measures the shape of objects with rough surface with the scanning speed of more than 100 mu m/s with the standard frame rate of 25 fps. The measurement uncertainty is comparable with that obtained with standard design.
