Investigation on Two-dimensional Counting and Tracking Laser Doppler Anemometry
In this paper, a newly developed two-dimensional Laser Doppler anemometry (2D-LDA) is reported, in which two components of the velocity are distinguished and measured by two closed optic-electro-hybrid-feedback loops containing the counting and tracking technique. As the bandwidth of photocurrent is compressed more than one order, the new 2D LDA system is simplified and lower cost besides the stable and reliable operation. Experimental study has been carried out to confirm the working principle of the system.
