Microscopic images of a test chart hidden behind a slab of a highly scattering medium were significantly improved by incorporation of a spatial filter located at the back Fourier-transform plane of the objective lens of a microscope. The image quality was shown to be improved further by detection of only the early-arriving photons through time-resolved detection in combination with spatial filtering.
