Broadening of the Measured Frequency Spectrum in a Differential Laser Anemometer due to Interference Plane Gradients

By Hanson, Steen Grüner1

From

Risø National Laboratory for Sustainable Energy, Technical University of Denmark1

It is shown how an inaccurate alignment of a differential laser anemometer may cause a significant broadening of the Doppler spectrum. The reason is the appearance of gradients in the interference pattern in the measuring volume. The phenomenon was investigated theoretically, and a method to measure these gradients is presented.
