| Zusammenfassung | A real time profile sensor capable of measuring the flow velocity at many points simultaneously is presented. In contrast to standard Doppler Global Velocimeter applications the sensor described here uses only one detector unit, namely a single avalanche photo diode array, and requires no reference detector. The simpli-fied sensor uses a frequency modulation of the laser source and measures the Doppler shift by evaluating the amplitude modulation of the scattered light having been transmitted through the absorption cell. |
