【摘要】 研究和建立了以几何光学近似光散射理论为基础的激光相位多普勒空间干涉条纹模型。计算得到了微粒对激光散射的空间相干条纹图形与粒径及散射参数的依从关系。将其应用于研制的双检测器相位多普勒实验系统 ,给出了系统功能和典型的实验结果更多还原

【Abstract】 A theoretical model of laser phase- doppler sizing anemometer based on the geometrical optics approxi- mation of light scattering is studied.The fringe patterns scattered by the particle are computed in relation with the particle diameter and optical parameters.An experimental phase- doppler system with two detectors is devel- oped.System functions and typical experimental results are also presented.更多还原
