For a congruence of straight lines defined by a hypersurface in \({\mathbb{R}}^{n+1}\), n ≥ 1, and a field of reflected directions created by a point source we define the notion of intensity in a tangent direction and introduce elementary symmetric functions Sm, \(m = 1, 2, \ldots , n\), of principal intensities. The problem of existence and uniqueness of a closed hypersurface with prescribed Sn is the “reflector problem” extensively studied in recent years. In this paper we formulate and give sufficient conditions for solvability of an analogous problem in which the mean intensity S1 is a given function.
