We consider aspects of using the method of anemometry on particle images to measure the velocity fields of nonstationary air vortices. To prevent the loss of a cross-pair when a particle passes through a light curtain, a method is proposed for determining the time delay between frames. Methods for measuring the velocity fields of nonstationary air vortices are described taking into account the vertical velocity of particles when the actual velocity is reproduced from the measured horizontal projection in the case of using a two-dimensional (single-chamber) type of anemometry method.
