摘　　要：纹影技术是空气动力学和热动力学研究实验中最常应用的一种流场成像方法,它也是一种非接触式的光学测量方法。本文设计出一种高精度便携式调节装置,既能满足测试区的观察口径,又能显著缩小尺寸的彩色纹影成像装置,从而提高纹影仪的现场适应能力,实现纹影技术在不同复杂流场中的展示,为进一步精确有效研究纹影技术的理论分析打下良好的设备基础。Schlieren technique is one of the most commonly used flow imaging methods in aerodynamic and thermodynamic research experiments,and it is also a non-contact optical measurement method.In this paper,a high-precision portable adjusting device is designed,which can not only meet the observation aperture of the test area,but also significantly reduce the size of the color schlieren imaging device,thus improving the field adaptability of the schlieren instrument,realizing the display of schlieren technology in different complex flow fields,and laying a good equipment foundation for further accurate and effective theoretical analysis of schlieren technology.
