  Imaging with optical resolution through highly scattering media is a long
sought-after goal with important applications in deep tissue imaging. Although
being the focus of numerous works, this goal was considered impractical until
recently. Adaptive-optics techniques which are effective in correcting weak
wavefront aberrations, were deemed inadequate for turbid samples, where complex
speckle patterns arise and light is scattered to a large number of modes that
greatly exceeds the number of degrees of control. This conception changed after
the demonstration of focusing coherent light through turbid media by
wavefront-shaping, using a spatial-light-modulator (SLM). Here we show that
wavefront-shaping enables widefield real-time imaging through scattering media
with both coherent or incoherent illumination, in transmission and reflection.
In contrast to the recently introduced schemes for imaging through turbid
media, our technique does not require coherent sources, interferometric
detection, raster scanning, or off-line image reconstruction. Our results bring
wavefront-shaping closer to practical applications, and realize the vision of
looking 'through walls' and 'around corners'.
