The tables of vibration modes for a blade obtained by the experimental method of holographic interferometry and systematized according to the number of nodal lines are presented. The graphical dependences of resonant frequencies that allow eliminating the vibration mode miss are presented. The vibration modes for a rectangular plate and a blade are compared. A technique of determining the resonant frequency for a missed harmonics is proposed.
