Abstract: A method for the laser Doppler real-time visualisation of the velocity field of moving media was developed. The method is based on the optical frequency demodulation of the optical fields forming the image of the investigated cross section. The visualiser was constructed on the basis of a semiconfocal optical cavity. The results of the visualisation of the velocity field of a vortical flow in a cylindrical channel are presented.
