direction in heavy-ion collisions can be determined only coarsely, any attempt to measure 3D differential distributions, including over azimuthal angle, will yield blurred results. Deblurring procedures, analogous to those in optics, are proposed to correct
for the coarse reaction-plane procedures and, simultaneously, for any instrumental inefficiencies, to arrive at 3D distributions tied to the true reaction plane. The refined 3D picture of the collisions can yield better access to the physics than the current
method of azimuthal moments. Broader applications of deblurring in nuclear physics are expected in other cases where signals in measurements are degraded by instrument performance or methodology, with the three-body decay-energy spectrum of 26O provided as
a direct example. Progress has been made in the space-time inference from two-particle correlations through deblurring.</span></p>
