Abstract

The invention relates to an apparatus for concentrating cosmic radiation originating from a celestial object, said apparatus comprising: a concentrating optical surface able to reflect incident cosmic radiation toward a target surface O′X′Y′, and liable to contain local surface errors and aiming and orientation errors; a system for inspecting the reflective optical surface; means for acquiring images of the optical surface from various viewpoints M′_mn (X′_mn, y′_mn) that are located on the target surface, m varying from 1 to M and n varying from 1 to N, so as to obtain M×N images of the optical surface illuminated by the cosmic radiation, with M viewpoints along X′ and N viewpoints along Y′, where M>1, N>1 and M·N≥30; and a unit for processing the M·N acquired images, which unit is suitable for: calculating the slopes δΔ(P)/δx and δΔ(P)/δy for each point P(x,y) of the reflective optical surface, where:
