| Abstract: | By using the derivative method, we obtained the same result with that of the previous work of Chen et al. in 2006. Different from the integral form, thederivative form of the surface expression published in this paperis derived from differential equation and based on the theory ofnon-imaging focusing heliostat proposed by Chen et al. in 2001.The comparison of the derivative form of fixed aberrationcorrection surface has been made with that of integral formsurface as well as that of spherical surface in concentrating the solar ray. |
