Abstract
The application relates to a method for determining at least one speed component of a fluid stream, in particular for laser Doppler anemometry, the method having at least the steps of: —providing at least a first part-beam and a second part-beam; —directing the first part-beam along a first optical path and directing the second part-beam along a second optical path onto a superimposition region within the fluid stream so that the first optical path and the second optical path intersect in the superimposition region; —detecting a Doppler-shifted first part-beam scattered light signal, which was back-scattered by tracer particles in the fluid stream in the superimposition region, at least partially following the first optical path; —detecting a Doppler-shifted solid angle scattered light signal, which was scattered by the tracer particles in the superimposition region into a path different at least from the first optical path and from the second optical path. The application also relates to a corresponding device.
