We propose a new express method of the correlation characterization of the particles suspended in the volume of optically transparent medium. It utilizes inline digital holography technique for obtaining two images of the adjacent layers from the investigated volume with subsequent matching of the cross-correlation function peak-to-basement ratio calculated for these images. After preliminary calibration via numerical simulation, the proposed method allows one to quickly distinguish parameters of the particle distribution and evaluate their concentration. The experimental verification was carried out for the two types of physical suspensions. Our method can be applied in environmental and biological research, which includes analyzing tools in flow cytometry devices, express characterization of particles and biological cells in air and water media, and various technical tasks, e.g. the study of scattering objects or rapid determination of cutting tool conditions in mechanisms.

基于峰底比的体积颗粒相关表征。
我们提出了一种新的表达悬浮在光学透明介质体积中的粒子的相关特征的方法。它利用内联数字全息技术从所研究的体积中获取相邻层的两个图像,随后匹配为这些图像计算的互相关函数峰底比。通过数值模拟进行初步校准后,所提出的方法可以快速区分颗粒分布的参数并评估其浓度。对两种物理悬架进行了实验验证。我们的方法可应用于环境和生物研究,包括流式细胞仪中的分析工具、空气和水介质中颗粒和生物细胞的表达表征以及各种技术任务,例如散射物体的研究或切削工具的快速测定机制上的条件。
