Abstract

A method for laser Doppler real-time visualization of the velocity field of moving media was developed. The method is based on the optical frequency demodulation of the optical fields formation of the image of investigated cross section. The visualizer was constructed on the basis of a semiconfocal optical cavity. The results of the visualization of the velocity field in the Ranque vortex flow are presented.
