In this paper we present the design and principle of a new anemometer, namely the 2d-Laser Cantilever Anemometer (2d-LCA), which has been developed for highly resolved flow speed measurements of two components (2d) under laboratory conditions. We will explain the working principle and demonstrate the sensor's performance by means of comparison measurements of wake turbulence with a commercial X-wire. In the past we have shown that the 2d-LCA is capable of being applied in liquid and particle-laden domains, but we also believe that other challenging areas of operation such as near-wall flows can become accessible.

The 2D Laser‐Cantilever‐Anemometer (2D‐LCA) was developed to measure flow velocities in two dimensions. A sensitive meausuring principle adopted from atomic force microscopes allows a spatial and temporal resolution comparable to modern x‐wire anemometry. (© 2009 Wiley‐VCH Verlag GmbH & Co.
