Abstract:
A method for analyzing a flow in at least one of a fluid and a gas for providing at least one of a three-dimensional determination of velocity components of the flow and a three-dimensional visualization of the flow, the method comprising:arranging spatially one after another in a detection space at least two roughly parallel light planes, and generating temporally the at least two roughly parallel light planes one after another using electromagnetic radiation of a predefined color; and scanning the detection space using the at least two roughly parallel light planes, and detecting electromagnetic waves that are at least one of partially emitted and scattered by particles that are contained in the detection space and that characterize the flow using at least one image detector, wherein in the step of scanning, changing as a function of time at least one of a frequency, a frequency spectrum and an intensity detected by at least one of the at least one image detector of the electromagnetic waves that are at least one of partially emitted and scattered by the particles.
