Abstract:
     The invention discloses a Doppler anemometer laser radar structure and detecting method based on F-P etalon, which is characterized by the following: the optical path contains Nd: YAG laser to output two beams of laser, wherein one beam is launched towards sky through two-dimensional scanning unit of plane reflector; the other beam laser intersects the input end of two-in-one optical fiber coupler through optical fiber; the optical fiber receiving port is loaded at the focus point of telescope cylinder with the optical fiber intersecting the input end of two-in-one optical fiber coupler; the output end of two-in-one optical fiber coupler connects collimating mirror through optical fiber, whose optical path loads color filter, beam splitting piece at 4:1 transparent-reflect rate, F-P etalon; one rectangle reflecting lens is set in the reflecting optical path of transparent optical path and beam splitting piece of etalon separately with one photon count detector setting on two sides of reflecting surface of each rectangle reflecting lens; the output end of photon count detector intersects data gathering and disposing equipment; the invention adopts double-brink technology to detect the layout of tropospheric atmospheric wind field directly.
