The invention relates to a split type automatic zooming 360-degree rotating optical wedge scanning laser wind measurement radar. An optical fiber probe and optical wedge scanning are integrally designed into a detection mechanism, and the detection mechanism and a 360-degree rotating hollow motor are arranged above a fan and are used for measuring wind in different directions. Control, acquisition, signal processing, a laser light source, a detector and the like are designed into a whole to be called as an acquisition processing part which is arranged in a fan. Internal and external devices are connected through optical fibers to acquire optical signals. According to the invention, atmospheric wind field measurement in different distance areas around the fan can be realized, and accurate data support is provided for the functions of fan yaw control, fan load reduction, auxiliary fan master control, efficiency curve test and the like, so that the efficiency of the wind turbine generatoris effectively improved.
