Abstract
The paper describes the optoelectronic discrete phase method for measuring deformation of blades of rotating bladed-disc assemblies of turbomachines. Advantages and disadvantages of different versions of optoelectronic discrete phase method realization are dealt with. Acriterion relating parameters of the reflecting surface to the radiator wavelength and making it possible to formulate the conditions necessary for the implementation of the method is introduced. Several circuit diagrams of devices for the realization of the method are presented.
