Query: Deep and optically resolved imaging through scattering media by
  space-reversed propagation   We propose a novel technique of microscopy to overcome the effects of both
scattering and limitation of the accessible depth due to the objective working
distance. By combining Laser Optical Feedback Imaging (LOFI) with Acoustic
Photon Taging (APT) and Synthetic Aperture (SA) refocusing we demonstrate an
ultimate shot noise sensitivity at low power (required to preserve the tissues)
and a high resolution beyond the microscope working distance. More precisely,
with a laser power of 10mW, we obtain images with a micrometric resolution over
~8 transport mean free paths, corresponding to 1.3 times the microscope working
distance. Various applications such as biomedical diagnosis, research and
development of new drugs and therapies can benefit from our imaging setup.
