Method of laser diagnostics of dynamic forms of hydraulic generator rotor is proposed. Measurement of shaft runout to determine the trajectory of the axis of rotation of the shaft. This method allows to measure the surface geometry of the fast moving rotor the hydraulic unit in real time with high precision without interfering with the structure of the generator.

Keywords: laser diagnostics, beating shaft, hydro, triangular sensor trajectory axis of rotation, the geometry of the surface of the rotor
