  In heavy-ion collisions, low relative-velocity two-particle correlations have
been a tool for assessing space-time characteristics of particle emission.
Those characteristics may be cast in the form of a relative emission source
related to the correlation function through the Koonin-Pratt (KP) convolution
formula that involves the relative wave-function for the particles in its
kernel. In the literature, the source has been most commonly sought by
parametrizing it in a Gaussian form and fitting to the correlation function. At
times the source was more broadly imaged from the function, still employing a
fitting. Here, we propose the use of the Richardson-Lucy (RL) optical
deblurring algorithm for deducing the source from a correlation function. The
RL algorithm originally follows from probabilistic Bayesian considerations and
relies on the intensity distributions for the optical object and its image, as
well as the convolution kernel, being positive definite, which is the case for
the corresponding quantities of interest within the KP formula.
