Abstract: | An imaging Doppler lidar (IDL) enables the measurement of the velocity
distribution of a large volume, in parallel, and at high spatial
resolution in the wake of a wind turbine. Because the IDL is
non-scanning, it can be orders of magnitude faster than conventional
coherent lidar approaches. Scattering can be obtained from naturally
occurring aerosol particles. Furthermore, the wind velocity can be
measured directly from Doppler shifts of the laser light, so the
measurement can be accomplished at large standoff and at wide
fields-of-view. |
