Selecting the Right Waves (IMAGE) Institute for Basic Science Caption a) The goal of this study is to enhance the intensity of wave (3) over (1), (2) and (4), as (3) is the only wave which hit the target and thus contains information about it. b) IBS scientists took advantage of the different times it takes for the waves to be refracted back. Thanks to this technique, the wave which hits the target (wave 3) can stand out from the other waves. The final images show simulations with untargeted light signals (c) or targeted waves, equivalent to wave 3 (d). Compared to c), the waves in d) are less diffused laterally and reduce their intensity with increasing depth.
