New developments in  laser anemometry which are based 
on digital technologies of input and processing of images using CCD 
chambers and personal computers are analyzed. The capabilities of 
digital dynamic speckle photography are illustrated by the intensity 
fields obtained for surface blood flow in biotissues. Two-phase flows 
are investigated with the use of a new PIV technique. New developments 
in the field of laser anemometry which are based on the use of coherent 
optical Doppler processors and enable us to pass from the local diagnostics 
to the diagnostics of two-dimensional fields of velocity and its visualization 
are described.
