Abstract
A method is described for determining information about a rotational speed of a compressor, in particular a turbocharger, by providing a measuring signal, in particular a microwave measuring signal, which is directed at a compressor impeller of the compressor, so that the measuring signal is reflected on revolving blades of the compressor impeller, detecting the measuring signal reflected by one or more blades, and determining the information about the rotational speed as a function of the reflected measuring signal.
