Abstract: At the DLR Solar Furnace, calorimeters or circular foil radiometers are used for calibrating video camera based flux mapping systems. For many years, we have been investigating the accuracy of ...

Abstract: The correct selection of the operating wavelength is essential for a precise pyrometric temperature measurement on solar irradiated samples, as the measurement may be disturbed by reflected solar ...

Abstract: Solar thermal energy systems often use optical imaging concentrators. The image size and shape produced in the focal plane of the concentrator system depends on the solar brightness distribution. ...

Abstract: Analysis of geometry and optical properties of solar parabolic trough collectors uses a number of specific techniques that have demonstrated to be useful tools in prototype evaluation. These are ...

Abstract: In order to optimize the solar field output of parabolic trough collectors (PTCs), it is essential to study the influence of collector and absorber geometry on the optical performance. The ...
