Imaging using a diffusing medium: sketch of the experimental setup. A diffusing object is placed at a distance ẑ + Δẑ from a diffuser and is illuminated by a spatially incoherent narrowband light source. A reference point source, which is incoherent to the object beam and is laterally shifted by r̂0 from the object, is placed in the reference plane at a distance 
from the diffuser. Speckle intensities are detected by an image sensor at distances z and z + Δz downstream from the diffuser.
