The aspherically-focused active area is calculated to obtain the best focusing effect at a given location in the material with a given refracted angle, through a flat, cylindrical or toric interface.
Moreover, a wide transducer aperture combined with Fermat concept allows very high lateral resolution and signal-to-noise ratio.
It is typically used in immersion with pulse echo technique, but can also be used in contact with a delay line.
