摘要
从实验上研究了干涉粒子成像技术(IPI)的最大可测粒子尺寸.分析了同一视场中不同物面导致的物距变化对IPI最大可测粒径的影响.搭建了单光束照射的IPI实验系统,对粒子直径为51μm和110 μm的聚苯乙烯混合粒子场进行测量,分析了同一视场内不同采集区域的最大可测粒径.实验结果表明,IPI技术最大可测粒径受实验系统物距影响,对于一固定参数的实验系统,同一视场内不同采集区域的最大可测粒径不同.
This study experimentally investigates the maximum measurable particle size of interferometric particle imaging(IPI).The maximum measurable particle size for IPI was examined in relation to the effect of object distance variation brought on by several object planes in the same field of vision.The IPI experimental system irradiated by a single beam was built to measure the polystyrene mixed particle fields with particle diameter of 51μm and 110μm,and the maximum measurable particle size in different collection areas in the same field of view was analyzed.The outcomes of the experiment demonstrate that the spatial relationship between the objects in the experimental system has an impact on the maximum quantifiable particle size of IPI technology.The maximum quantifiable particle size of various acquisition areas within the same field of view varies for an experimental system with fixed parameters.
