摘　　要：基于纹影仪的基本原理,分析造成纹影仪成像质量不佳的原因,提出了在光源部分加装自聚焦透镜的解决方法。深入分析并计算了加装自聚焦透镜后汇聚光斑的大小,同时,为装调方便设计了同轴夹装调整架。通过实验验证,加装了自聚焦透镜后,在加热平台处于60℃和90℃两种温度下,纹影仪的成像质量均有明显的提升,所见空气扰动更为清晰明显。Based on the basic principle of Schlieren apparatus, the causes of poor Schlieren instrument image quality are analyzed, and the light source parts with focusing lens solutions is proposed. In-depth analysis and calculating the size of the adding together after focusing lens flare, at the same time, for convenient adjusting, a coaxial clamp design frame is designed. Through the experiment of the entire system, after the focusing lens and two kinds of temperature at 60℃ and 90℃ in heating platform, the imaging quality is obvious improved, air turbulence is observed more apparently.
