Paper Abstract

We present a method for testing the shape quality of the reflecting surface of a parabolic trough solar collector (PTSC) with flat null-screens. We develop a custom algorithm to reconstruct the surface taking into account the differences between the normal vector of the true surface and the reference one. Also, we perform a numerical simulation to analyze the accuracy of the method by introducing controlled systematic errors such as misalignments of the null-screen or the CCD plane.
