Derivation of Error Sources from Experimentally Determined Heliostat Surface Shapes

Cumpston, Jeffrey; Coventry, Joseph


Data gathered using photogrammetry that represents the surface and structure of a heliostat mirror panel is investigated in detail. A curve-fitting approach that allows the retrieval of four distinct mirror error components, while prioritizing the best fit possible to paraboloidal terms in the curve fitting equation, is presented. The angular errors associated with each of the four surfaces are calculated, and the relative magnitude for each of them is given. It is found that in this case,...[Show more]
