A. біоспекли динаміка спеклів спеклові поля bio-speckles dynamic speckles speckle fields speckle metrology The review of the works covering the application of methods and ideas of speckles' metrology in various fields of science and technology is completed. In particular, a special attention is paid to the analysis of the applications of speckles (bio-speckles) in biology and medicine. A very important area of the science of speckle is to be mentioned, namely, the speckle fields that develop over time (dynamic speckles) and arise from moving objects and from scatterers with variable refractive index. The dynamic speckle methodology allows one to effectively solve problems related to the dynamics of seed change, fruit rot, parasitic activity and many others. Possibilities for measuring cerebral blood flow through a partially transparent unopened part of the skull of a rat using the temporal contrast method are described. The results of the measurements can be supplemented by gentle surgical penetration into the rat skull to directly measure hemoglobin concentration and internal cranial pressure. It should be noted that the Doppler’s effect plays a major role in measuring the parameters of the capillary blood flow with help of analyzing the behavior of dynamic speckles. Speckle analysis, in dynamics, is successfully used in the study of processes of microcirculation in the retina, in the study of atherosclerosis plaques on the aorta of people in forensic examination, as well as in the analysis of suspensions of human erythrocytes. There are results on the application of the method of dynamic speckles in endoscopic studies and laser imaging of internal tissues. The second part of the review is devoted to the analysis of the state of work in the field of speckle fields obtained from objects of inorganic nature. The speckle dynamics methods are used to monitor deformations, displacements, vibrations, stresses, oxidation processes, paint drying, evaporation, and mass loss. Traditionally, non-biological materials are objects with low transparency (inks, metals in the state of corrosion, cement in the state of hydration, foams, etc.), that imposes appropriate restrictions on the use of direct light scattering geometry. At the same time, the problems are successfully solved by modern optical metrology. It is quite obvious that there are a large number of application areas where the analysis of speckle fields can serve as a useful application in the tasks of appropriate non-contact metrological measurements.

Зокрема, особливу увагу спрямовано на аналіз застосувань спеклів (біоспеклів) у біології і медицині. Заключну частину огляду присвячено роботам з дослідження динаміки спеклів в об’єктах неорганічної природи. Вказано на загальну перспективність використання спеклів як потужного не руйнуючого оптичного дослідницького методу.

The review of the works covering the application of methods and ideas of speckles' metrology in various fields of science and technology is completed.
