    Abstract: A wind turbine blade is provided which comprises a main blade portion and a light detection and ranging (LIDAR) element, the main blade portion having a shell defining an outer aerodynamic surface of the blade, and the LIDAR element being disposed within a volume bounded by the outer aerodynamic surface and comprising at least one LIDAR system configured to transmit light beams away from the blade and to detect reflected light beams incident upon the blade, wherein the shell comprises at least one aperture extending at least partly through a thickness of the shell and containing optically transparent material, wherein the at least one LIDAR system is disposed within a volume bounded by an inner surface of the shell and is positioned to transmit and detect light beams through the optically transparent material, wherein the LIDAR element comprises a housing coupled to a surface of the blade within the volume bounded by the inner surface of the shell, the housing comprising a gyroscope mechanism coupled to the at least one LIDAR system such that an orientation of the at least one LIDAR system is substantially unaffected by movement of the blade so as to vary an angle at which light beams are transmitted through the optically transparent material as the blade moves.
