Unique determination of a time-dependent potential for wave equations from partial data

We consider the inverse problem of determining a time-dependent potential $q$, appearing in the wave equation $\partial_t^2u-Δu+q(t,x)u=0$ in $Q=(0,T)\timesΩ$ with $Ω$ a $C^2$ bounded domain of $\mathbb R^n$, $n\geq2$, from partial observations of the solutions on $\partial Q$. We prove global unique determination of a coefficient $q\in L^\infty(Q)$ from these observations.
