The single Fabry-Perot interferometer(FPI)double-edge structure in incoherent Mie Doppler wind Lidar is investigated theoretically.It has proved that,by reducing the divergence of nonzero angle beam of this structure appropriately,the deficiency caused by the asymmetric edge curves can be made up effectively and can have approximate equal measurement accuracy with the double FPIs double-edge structure.It also has proved that the Lidar system with this structure can tune the measuring dynamic range for wind velocity requirement to reach as high measurement accuracy as possible and has a strong adaptability.
