White-Light-Interferometry (WLI) requires a big amount of raw data, which contradicts the demands for increasing measurement speed and bigger number of pixels. Meanwhile, 4 Megapixel cameras are available with a continuous framerate greater than 100 frames per second. With conventional sampling, this would allow a measurement speed of 'only' 20µm/sec. We will demonstrate that this limit can be overcome by factor of about 30. We achieve a measurement speed of more then 500µm/sec by a novel undersampling scheme. We present results from electronics and automotive applications.
