The process of contrast formation for spherical particles in reflection scanning acoustic microscopes is investigated. It is shown that in reflection acoustic microscopes the image formation of spherical particles is quantitatively well described by the Fourier optics methods. The center image of a sphere shows the Fourier transformation of the squared pupil function. The images in the top are similar to the OTF of the confocal microscopical system. The contrast of the image obtained in a middle position exhibits the pupil function in square.
