Abstract
This review is devoted to the analysis of the history and current trends in the development of the velocimetry method based on particle images for an aerodynamic experiment. The authors consider the basics of the method, various implementations, former and current status of equipment. Special attention is paid to the methods of data processing and evaluation of various physical values in the flow from the measured velocity fields. The paper briefly analyzes some optical methods that can be used together with velocimetry based on particle images and are implemented using similar equipment. The main focus of the review is set on the works that demonstrate the potential and the current level of the anemometry method based on particle images in the context of an aerodynamic experiment.
