A High-Resolution Optical Measurement System for Rapid Acquisition of Radiation Flux Density Maps (Poster)
No full textTo identify the power and flux density of concentrated solar radiation the Institute of Solar Research at the
German Aerospace Center (DLR - Deutsches Zentrum für Luft- und Raumfahrt e. V.) has used the camera-based
measurement system FATMES (Flux and Temperature Measurement System) since 1995. The disadvantages of low
resolution, difficult handling and poor computing power required a revision of the existing measurement system. The
measurement system FMAS (Flux Mapping Acquisition system) is equipped with state-of-the-art-hardware, is
compatible with computers off-the-shelf and is programmed in LabView. The expenditure of time for an image
evaluation is reduced by the factor 60 compared to FATMES. The new measurement system is no longer associated with
the facilities Solar Furnace and High Flux Solar Simulator at the DLR in Cologne but is also applicable as a mobile
system. The data and the algorithms are transparent throughout the complete process. The measurement accuracy of
FMAS is determined to at most +/- 3 % until now. The error of measurement of FATMES is at least 2 % higher according
to the conducted comparison tests
