Mirror for concentrating sun's rays on small focus

摘要

The rings are assembled from the interchangeable plates. The structure forms them into a precisely conical or round paraboloid surface. The bundled sunrays are spectrally divided with the aid of prisms (15), can be arranged to fall on a circular surface (16). The main part of the supporting structure can be an inflated inverted-toroidal round hollow body with a meridional curve determined by a formula based on Cartesian coordinates. The body wall can consist of overlapping interchangeable elastic sheet-sections enclosed by a three-dimensional chain with solid and flexible links.
