Query: Imaging dynamics beneath turbid media via parallelized single-photon
  detection   Noninvasive optical imaging through dynamic scattering media has numerous
important biomedical applications but still remains a challenging task. While
standard diffuse imaging methods measure optical absorption or fluorescent
emission, it is also well-established that the temporal correlation of
scattered coherent light diffuses through tissue much like optical intensity.
Few works to date, however, have aimed to experimentally measure and process
such temporal correlation data to demonstrate deep-tissue video reconstruction
of decorrelation dynamics. In this work, we utilize a single-photon avalanche
diode (SPAD) array camera to simultaneously monitor the temporal dynamics of
speckle fluctuations at the single-photon level from 12 different phantom
tissue surface locations delivered via a customized fiber bundle array. We then
apply a deep neural network to convert the acquired single-photon measurements
into video of scattering dynamics beneath rapidly decorrelating tissue
phantoms. We demonstrate the ability to reconstruct images of transient
(0.1-0.4s) dynamic events occurring up to 8 mm beneath a decorrelating tissue
phantom with millimeter-scale resolution, and highlight how our model can
flexibly extend to monitor flow speed within buried phantom vessels.
