摘要
讨论了同轴数字全息术测量PM2.5大气可吸入颗粒物的可行性,并设计了一套针对PM2.5颗粒测量的同轴数字全息实验装置。在讨论同轴全息图的数字图像处理方法基础上,利用所设计的装置测量了与PM2.5颗粒粒径相当的标准粒子,对实验结果进行了分析和讨论。实验证明,同轴数字全息术可有效应用于PM2.5颗粒的测量与分析。
Abstract
In this paper, the feasibility to measure PM2.5 by using in-line digital holography is discussed and a corresponding experimental setup is designed. The setup is used in the measurement of standard particles which have approximate diameters with PM2.5. The experimental results are discussed and analyzed too. The results show that in-line digital holography can be effectively applied to the measurement of PM2.5.
