Abstract: A LIDAR measuring device and a method for determining the speed of particles in a measuring volume includes a narrowband continuous wave laser light source (1), which emits light which is coupled into a measuring branch (3) and a reference branch (4). The light coupled into the measuring branch (3) is at least partially emitted by a transmitting device in the direction of the measuring volume such that the emitted light is at least partially scattered and/or reflected by the particles in the measuring volume. A part of the scattered and/or reflected light is then received by a receiver device and is coherently superimposed with the light leaving the reference branch (4), and the resulting light beam is directed onto a detector (6) to generate a detector signal characteristic for the resulting light beam. Finally, the speed of the particles in the measuring volume is determined in an evaluation unit (11) by taking into account the detector signal.
