MOST existing methods of calibrating vibration pick-ups employ some form of extrapolation, that is, the pick-up is calibrated at low frequencies, where the amplitude can be made large, and the result ...

White light interferometry (WLI) is a contact-free optical method for measuring surface height. It uses the phase difference between the light reflected off a reference mirror and the target sample to ...
