Paper Abstract

Optical spatial frequency (correlation) filtering techniques identify a class of noncontact vectorial velocity sensors. Detectors according to this optical measuring method are characterized by a fast measurement with a small dead time and low measurement uncertainty. For the purpose of measurement, the sensors determine the relative displacement of any randomly structured surface with respect to the sensor. The use of newer filter structures can reduce the measurement uncertainty.
