Patent number: 10921585Abstract: A generally time-varying boundary surface between a plurality of flowing fluids having different refractive indices, e.g. the boundary surface between water and air with an open water surface, produces an optical disturbance. Optical flow measurement procedures that occur through the boundary surface are affected by this disturbance, which can lead to significant measurement deviations or can even completely prevent a measurement from being made. The invention contributes to solving this metrological problem by proposing arrangements and methods for instantaneous, hardware-based correction of optical disturbances caused by a fluctuating boundary surface. For this purpose, a wavefront modulator is introduced into the beam path of the optical measuring method, the modulator actively compensating for the optical disturbance by means of a control system. The invention makes it possible to perform optical flow measurements through a fluctuating boundary surface.Type: GrantFiled: July 10, 2018Date of Patent: February 16, 2021Assignee: TECHNISCHE UNIVERSITÄT DRESDENInventors: Lars Büttner, Jürgen Czarske, Martin Teich, Nektarios Koukourakis
