中文摘要:
研究了基于激光条纹成像的风速测量技术,根据Fizeau干涉仪透射率函数和大气中的分子散射光谱特征对其优化设计,得到了一套基于任意光束入射的Fizeau干涉仪的系统参数。优化设计结果为Fizeau干涉仪腔长12 mm,平板反射率0.65。最后模拟了该Fizeau干涉仪对分子和气溶胶的联合测量能力。模拟仿真结果表明,在20 mJ、100 Hz重复频率和接收口径200 mm条件下,风速测量误差为1 m/S,探测高度为17.8 km。

英文摘要:
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.
