Using a Laser-Cantilever-Anemometer for two dimensional measurements in turbulent flows

We present an improved version of the Laser-Cantilever-Anemometer which allows for measurements in two dimensions. By replacing a one dimensional PSD (Photo Sensitive Detector) with a two dimensional one, additional information about the direction of the local flow can be determined. Measurements carried out with the improved Laser-Cantilever-Anemometer in comparison to X-wire measurements are presented.
