    • High efficiency Lamb wave lens for subsurface imaging 

      Atalar, Abdullah; Koymen, H. (IEEE, 1989-10)
      A conventional scanning acoustic microscope lens excites all the possible modes of acoustic waves in the solid structure under examination. The excited leaky modes contribute significantly to the high contrast obtained in ...
    • The V-Groove lens 

      Bozkurt, Ayhan (Bilkent University, 1994)
      Primarily designed for imaging purposes, the acoustic microscope finds application in the qualitative evaluation of materials, too. The lens response as a function of defocus, which is known as the V{z) curve, is formed ...
