全息定标非实时定标粒子场图像标准丝 holography scaling non-in-time scaling reconstruct particle image standard wire

摘要

在粒子场的定量分析中, 通常采用外加标准丝作为粒子尺寸测量的定标尺度。为了解一定景深范围内存在的标准丝再现像实验测量结果的影响, 从理论和实验上详细分析了标准丝再现像在不同位置处的强度分布及变化, 指出了常规定标方法对粒子场图像数据所带来的影响, 同时提出了一种新的定标方法——非实时定标方法。实验结果表明, 非实时定标方法在保持空间定位精度的基础上, 测量得到的标准粒子尺寸的不确定在4%左右。该方法有效地解决了标准丝再现像对粒子尺度测量精度影响问题, 可以用于粒子场实际测量工作中。

Abstract

For quantitative analysis in the particle field, a standard wire is generally used as the scaler for measuring the particle size. In order to understand the effect of the reconstructed wire with a certain depth of field on the experimental results, detail analysis of the intensity distribution and variation of the reconstructed wire at different positions are performed by theory and experiments. The influences of the normal scaling method on the particle image data are pointed out and a new scaling method, the non-in -time scaling manner, is given. Experiment results show that, the uncertainty of the particles size measurement is about 4% by keeping the precision of particle location. This new method can effectively solve the problem, which affects the precision of the particle size measurement. It can be used in practical measurements.
