The paper presents the results of application of optical system with brightness amplification, a laser monitor, to study the surface of aluminum nanopowder at the time of laser ignition and during combustion. Using a laser monitor, we visualized the presence of a liquid phase in the process of laser ignition of aluminum nanopowder combustion for the first time. For quantitative analysis of the combustion process, we propose using the correlation coefficient of the images of laser monitor. The results of calculating the correlation coefficient demonstrated compliance with the change in the intensity of the images of the laser monitor during combustion and visual observation of the combustion process. For the conventional scheme of a laser monitor with a focal length of 8 cm, the distortions introduced by the instability of the brightness amplifier into the measurement results are estimated. When observing a static test object, the correlation coefficient of the images varied from 0.995 to 0.996, while the fluctuation in the correlation coefficient during combustion is in the range from 0.685 to 0.996, which indicates the possibility of this parameter usage for quantitative analysis of combustion processes in the study using a laser monitor.

Application of digital speckle patterns correlation for blood clotting time evaluation

Iullia Liushnevskaya, Fedor Gubarev

Proceedings Volume 11845, 1184509 (2021) https://doi.org/10.1117/12.2588460

Read Abstract +

The paper discusses the experimental stage of developing a device for the non-contact assessment of blood clotting using the method of laser-speckle correlation. The device based on this method will have a number of advantages over existing hemostasis analyzers: it allows the analysis of plasma micro samples, citrated and native blood by a non-contact optical method. The results of experiments with blood plasma, citrate and native blood, aimed at practical development of the method are presented and discussed. It has been shown that the method of laser-speckle correlation is promising for the creation of a new device for assessing blood clotting.
