Abstract. The surfaces of the fin fragments of the Airbus A 320, Boeing 737-700 and Tu-214 are investigated using the interference method. The functional diagram of the measuring setup is given. The images of the surface microrelief are obtained and the distances to the surface are measured during its linear movement along the 0X axis relative to the optical pupil with a step of 100 μm, 20 measurements are performed at each point.
