A method for remote optical measurement of the geometry of nonimaging concentrators is presented. A concentrator installed in a solar tower was measured by observation of transmission patterns from the heliostat field, and comparison of the measured

We present an approach to find optimal reflector shapes for non-tracking solar collectors under practical constraints. We focus on cylindrical absorbers and reflectors with translational symmetry. Under idealized circumstances, edge ray reflectors ar

We present secondary concentrators with non-regular shapes for increasing the concentration of radiation from a given field of heliostats, well suited for partitioning the receiver into several units, arranged side by side. For a general heliostat fi

Secondary concentrators with non-regular cross section have been proposed to permit additional degrees of freedom in heliostat field design, free of the limitations imposed by conventional rotationally symmetric concentrators. A new class of concentr

We present asymmetric secondary reflectors made of plane facets for increasing the concentration of radiation from a field of heliostats. The reflectors are suited for partitioning the receiver in several parallel units. In the case of an asymmetric

An optical measurement for radiation concentrators is proposed. A Lambertian light source is placed in the exit aperture of the concentrator. By taking pictures of the concentrator as seen from a remote location one gets the transmission patterns whi

In solar tower plants, where a rotationally symmetric field of heliostats surrounds the tower, an axisymmetric secondary concentrator such as a compound parabolic concentrator (CPC) or a tailored concentrator or a cone is the obvious choice. For loca

Parabolic trough type solar power plants could reach higher efficiencies by using secondary reflectors, which increase the concentration of the solar irradiance onto the absorber tube. Recently, compact secondary concentrators have been proposed whic

Optics design plays a key role for the development of competitive products. Optical efficiency has strong influence on the lifetime cost of an LED street lamp and hence its marketability.
