Abstract
A device includes a light source () for generating light with a single wavelength; a modulator () for modulating the light generated into transmission light; a beam scanner () for carrying out beam scanning by which the transmission light modulated is radiated, and the light reflected is received; a beam scanning controller () for controlling the radiation direction; a signal processing unit () for performing wind measurement through heterodyne detection using the light generated and the corresponding received light; and an optical axis corrector () for correcting the optical axis angular shift between the transmission light and the received light, which accompanies the beam scanning, with respect to the received light used by the signal processing unit () or the transmission light used by the beam scanner (), on the basis of the radiation direction of the beam scanner (), the angular speed of the beam scanning and the wind measurement distance.
