Enhanced adaptive focusing through semi-transparent media


Adaptive focusing enables to focus light through opaque curtains. The maximum resolution of this process is limited by the effective numerical aperture of the system: the span of angles which contribute to the focusing. In a recent paper , we demonstrate, by exploiting a custom spatial filter, how it is possible to select, between the many light paths contributing to the adaptive focusing, the ones which provide the higher numerical aperture. This optical selection effectively improves the resolution of the adaptive focusing in the weak scattering regime.
