摘要
本文介绍了激光诱导荧光(LIF)技术测量水体浓度场、温度场和速度场的基本原理,总结了从一维到三维LIF技术的发展历程,综述了激光诱导荧光(LIF)技术测量水体标量场的关键问题,包括激光器和片光源、荧光物质选择和校正方法,从工程化和产业化的需求出发,提出了基于3DLIF技术的水体三维标量场测量仪器的总体技术方案、技术路线和总体技术指标,并给出了3DLIF的关键技术及其解决方案。
T his paper introduces the principle of the L IF technique to m easure the w ater concentration,tem perature and velocity fields,sum m arizes the L IF technology developm ent from ID to3D,reviews the key issues of L IF to m easure the scalar field in w ater,including laser and light-sheet sources?fluorescence m aterial selections and calibration m ethods,and finally reviews various correction m ethods of P L IF and3D LIF.Based on the3D LIF techniques,this paper proposes an overall technical schem e,technical route and overall technical indicators of3D LIF instru m en t,and then provides solutions of3D LIF key techniques to m eet the dem and of engineering and industrialization.
