Application of antenna arrays and organosilicon polymers as an immersion medium for ultrasonic testing of objects with rough surfaces.

The possibility for the application of an elastic organosilicon polymer (aquapolymer) as an immersion medium for providing a stable acoustic contact between a tested object with a rough surface and an antenna array in automated ultrasonic testing is considered. If the form of the surface is known, it can be accounted for in the C-SAFT method for the reconstruction of a reflector image using echo signals. A surface profile can be obtained by either direct measurement using a profilometer or by analysis of the reconstructed surface image. An algorithm for processing a surface that was reconstructed using the C-SAFT method is proposed for automatic acquisition of information on the profile of the surface. The operability of the proposed method of reflector-image acquisition with consideration of the rough surface of a tested object is demonstrated in model experiments. [ABSTRACT FROM AUTHOR]
