在这篇文章中，一个全面的不确定性分析将给出一个流行的二维粒子测量技术，称为干涉激光成像液滴尺寸（ILIDS）测量液滴和气泡。这包括对液滴非球形度影响的第一次估计。此外，还对频率测定和校准过程的不确定度进行了研究。为此，两个最常见的校准程序进行了实验比较。这表明，它往往支配总的不确定性。设计准则，然后得出有关的观察角度，出焦盘的大小和校准程序，这可能会导致一个组合的不确定性低于1.5%的液滴和2%的气泡。
In this article, a comprehensive uncertainty analysis will be given of a popular 2D particle measuring technique called Interferometric Laser Imaging for Droplet Sizing (ILIDS) for measuring droplets and bubbles. This includes the first estimates on the influence of droplet non-sphericity. Next to this, the uncertainty on the frequency determination and the calibration procedures were also investigated. To this end, the two most common calibration procedures were experimentally compared. This showed that it often dominates the total uncertainty. Design guidelines are then derived concerning observation angle, out-focus disk size and calibration procedure which could lead to a combined uncertainty below 1.5% for droplets and 2% for bubbles.
