本文提出了一种能够测量非对称喷雾场三维浓度与温度分布的新的测试方法──激光干涉层析技术。详细论述了利用这种技术进行任意非轴对称三维喷雾折射率场测量，及由折射车场及演浓度场与温度场的理论基础。指出了三维场的测量必须在多个方向上获取全息干涉图这一干涉层析技术的特点，讨论了各拍摄方向的夹角的选择问题，从而为三维瞬变喷雾场浓度与温度分布的测量提供了理论依据。 This paper presents a new test method that can measure the three-dimensional concentration and temperature distribution of an asymmetric spray field ─ ─ Laser Interferometry. This paper discusses in detail the measurement of the refractive index field of any non-axisymmetric three-dimensional spray using this technique, and the theoretical basis of the refraction yard, the concentration field and the temperature field. It is pointed out that the feature of interferometric tomography that the holographic interferogram must be obtained in many directions in the measurement of three-dimensional field is discussed. The selection of the included angle in each shooting direction is discussed. The measurement of concentration and temperature distribution in the three-dimensional transient spray field Provided a theoretical basis.
