    2D experiments with profile NACA0015 supported with two degrees of freedom in aerodynamic tunnel of suction type were realized. One degree of freedom was rotation around the profile axis in 1/3 chord distance behind the profile leading edge, the second one was the vertical translation. The interferometric visualization of the flow field in the vicinity of the profile during its self-excited vibration was realized. Forces acting on the profile and the pressure distribution on the profile surface resulting from the interferometric measurements are presented.
