  The capture of scintillation light emitted by liquid Argon and Xenon under
molecular excitations by charged particles is still a challenging task. Here we
present a first attempt to design a device able to grab sufficiently high
luminosity in order to reconstruct the path of ionizing particles. This
preliminary study is based on the use of masks to encode the light signal
combined with single-photon detectors. In this respect, the proposed system is
able to detect tracks over focal distances of about tens of centimeters. From
numerical simulations it emerges that it is possible to successfully decode and
recognize signals, even complex, with a relatively limited number of
acquisition channels. Such innovative technique can be very fruitful in a new
generation of detectors devoted to neutrino physics and dark matter search.
Indeed the introduction of coded masks combined with SiPM detectors is proposed
for a liquid-Argon target in the Near Detector of the DUNE experiment.
