Improvements on the validation of a nonintrusive laser-based measurement technique are presented. This new technique, called global rainbow thermometry (GRT), is capable of determining the temperature and the size distributions of liquid droplets dispersed in a liquid or gaseous bulk. We propose a new data inversion algorithm that takes into account the whole rainbow pattern. Experimental validation of the GRT technique is performed for a liquid-liquid suspension. We performed the validation by comparing the measurements obtained with the GRT technique for the mean droplet temperature and size with the results obtained with alternative techniques.
本文介绍了一种基于激光的非侵入式测量技术验证方面的改进。这种新技术称为全局彩虹测温法（GRT），能够确定分散在液体或气体主体中的液滴的温度和尺寸分布。我们提出了一种考虑整个彩虹图案的新数据反演算法。对液-液悬浮液进行了GRT技术的实验验证。我们通过将GRT技术获得的平均液滴温度和尺寸测量结果与其他技术获得的结果进行比较来进行验证。
