摘　　要：激光测速已广泛存在多相流动测量中,测量原理主要有相关性原理和多普勒原理,将两种测量原理分别与成像技术或光散射理论结合发展了多种测试技术。本文对基于激光的多相流测试技术在多相流动测量应用研究进展进行分析和综述,并对今后发展进行展望。粒子成像测速技术、激光多普勒测速仪、相位多普勒风速计等已成为多相流动参数测量的有效工具,激光诱导荧光技术在工程多相流动相分离领域应用前景较好。随着对多相流动机理认识的加深,三维粒子成像测速技术、全息粒子图像测速技术等将是今后多相流动测量领域发展的热点。Laser velocimeter has been widely used in multiphase flow measurement. Its measurement principle can be divided into the correlation principle and Doppler principle,and the combination of the two measuring principles and imaging technology or light scattering theory can develop a variety of measurement techniques. The application research progress of the multiphase flow measurement technology based on laser are analyzed and reviewed,and the future development is forecasted. Particle image velocimetry,laser Doppler velocimetry and phase Doppler anemometry etc. have become effective tools for the measurement of multiphase flow parameters. The laser induced fluorescence technique has good application prospect in the multiphase flow separating field. With the deep understanding for the mechanism of multiphase flow,three-dimensional particle imaging velocimetry,holographic particle image velocimetry etc. will be the focus in the development of multiphase flow measurement field in the future.
