| Popis: | The wind speed measurement technology based on laser stripe image is studied. According to the Fizeau interferometer transmittance function and atmospheric scattering spectrum function of molecular scattering spectral characteristics for its optimization design, We obtain a set of Fizeau interferometer system parameters based on any incident light beam. The cavity length is 12 mm, the reflectivity is 0.65 from plate and the apex is 10 murad. At last, under the condition of 20 mj, repetition frequency of 100 Hz and receiving diameter of 200 mm, the simulating results indicate that when wind velocity error is 1 m/s, the detection ability is 17.8 km above ground. |
