Method and device for flow analysis

A device for performing an analysis of a flow in a detection space, comprising:

• an arrangement for detecting electromagnetic waves that one of:
• i) at least partially emanate from, and ii) are scattered by particles that are contained in the detection space and that characterize the flow;
• at least one illuminating device for generating at least approximately parallel light sheets in accordance with the electromagnetic waves, the light sheets illuminating at least partially the detection space, and the electromagnetic waves including one of:
• i) different frequencies, and ii) different frequency spectrums, the at least one illuminating device generating the light sheets of either different frequencies or different frequency spectrums in temporal succession relative to one another;
• an arrangement for arranging the light sheets in spatial succession;
• and
• at least one detection device for recording two-dimensional images of at least one area of the detection space in one of:
• i) a frequency-selective manner, and ii) a frequency-band-selective manner.

A new method for performing an analysis of a flow in a detection space, comprising:

• detecting electromagnetic waves that one of:
• i) at least partially emanate from, and ii) are scattered by particles that are contained in the detection space and that characterize the flow;
• generating at least two roughly parallel light sheets in accordance with the electromagnetic waves, the electromagnetic waves including one of:
• i) different frequencies, or ii) different frequency spectrums, the at least two light sheets of either different sequences or different frequency spectrums being generated in temporal succession relative to one another and in spatial succession relative to one another;
• and
• scanning the detection space at least in areas using the at least two light sheets.
