在Plataforma Solar de Almeria（PSA）建立并运行了一个能够测量垂直于光轴的平面中的碟/斯特林系统的通量分布的通量映射系统。它采用间接测量方法，在光路中放置水冷朗伯靶，在聚光器上安装CCD相机，拍摄焦斑亮度分布的图像。通过计算来自碟形物的总功率并将其与整个测量区域上的积分灰度值相关联来进行校准。该系统在DISTAL II拉伸膜盘和新的EURODISH中成功运行，以表征其光束并改善其接收器上的通量分布。Copyright © 2002 by ASME
A flux mapping system able to measure the flux distribution of dish/Stirling systems in planes perpendicular to the optical axis was built and operated at the Plataforma Solar de Almeria (PSA). It uses the indirect measuring method with a water-cooled Lambertian target placed in the beam path and a CCD-camera mounted on the concentrator taking images of the brightness distribution of the focal spot. The calibration is made by calculating the total power coming from the dish and relating it to the integrated gray value over the whole measurement area. The system was successfully operated in a DISTAL II stretched membrane dish and in the new EURODISH in order to characterize their beams and improve the flux distribution on their receivers.Copyright © 2002 by ASME
