摘　　要：全场彩虹技术受限于单点区域测量,如何拓展其到多点测量甚至一维测量,对于其实用性具有重要的意义。对提出的全场彩虹系统一维化原理进行了分析,设计并搭建了一维全场彩虹测量系统。分析了系统参数的选择对彩虹图像的影响,并改进了标定方法。用该系统对乙醇喷雾在一维线区域的蒸发物理过程进行了定量研究,得到的结果与PDA测量结果进行了对比,符合实际物理现象。As global rainbow technology is restricted to area of single point measurement, thus how to expand it to multi-point measurement even one-dimensional measurement is of great importance for its practical usage. The one dimensional principle of global rainbow is analyzed. The one dimensional measuring system of global rainbow is designed and built. The influences of system parameters on the rainbow image are analyzed and calibration method is improved. The physical processes of ethanol spray evaporation in one-dimensional line region are studied quantitatively with the system. The results obtained are compared with the PDA measurements, and it is in line with the actual physical phenomenon.
