论文摘要
提出了可压缩,粘性和快速旋转气流(涡旋)的光学特性的实验研究。气体涡旋可以充当光学元素,例如镜头或波导。通过直接干涉相测量和梁传播分析确定光学性能。用Zernike多项式分析输出光束,以范围的气流参数(包括窒息流量)。测量了绝对径向气体密度分布,并证明了一种调整它的技术。
Experimental studies of the optical properties of compressible, viscous and rapidly-rotating gas flows (vortices) are presented. Gas vortices can function as optical elements such as lenses or waveguides. The optical properties are determined from direct interferometric phase measurements and beam propagation analysis. Output beams are analyzed in terms of Zernike polynomials for a range of gas flow parameters, including choked flow. The absolute radial gas density distribution is measured and a technique for adjusting it is demonstrated.
