COSMIC RADIATION CONCENTRATOR FACILITY EQUIPPED WITH A REFLECTIVE OPTICAL SURFACE MONITORING SYSTEM

摘要

The invention relates to a concentrating installation of radiation from a celestial object equipped with a concentrating optical surface (2) reflecting the incident radiation (3) towards a target surface, which can present local errors of surface, pointing, d and an optical surface control system which comprises: - means (4) for acquiring images (5) of the optical surface according to different points of view M'mn (x'mn, y ') mn) located in the target area, - an image processing unit able to: o calculate the slopes δΔ (P) / δx and δΔ (P) / δy: L (M'mn, P) being the luminance at a point of the image corresponding to the point P (x, y) of the optical surface (2) observed according to the point of view M'mn, ε0 the apparent angular radius of the celestial object, gx and gy of the coefficients, o to determine from these slopes, a local surface error and an adjustment error at the point P (x, y) of the optical surface (2).
