Beschreibung
Zusammenfassung:	A laser-doppler-anemometer for measuring the velocities of moving test specimens employing a laser beam source, deflection optics for at least two partial beams, collecting optics for focussing at least one of the partial beams on the test specimen, and a detector for the scattered light radiated from by the moving test specimen. A compact construction and further possible applications can be obtained when the laser beam source is provided by at least one laser diode whose temperature can be adjusted and kept constant with a temperature control circuit.
