Construction and testing of lightweight and low-cost pneumatically inflated solar concentrators... Further implementation of a flat and a cylindrical extension of the concentrating mirror as secondary mirrors was incorporated into the concentrator design in order to compensate for seasonal variations of collected radiation....
Measurement of mirror panels using coloured pattern deflectometryThis paper introduces the Coloured Pattern Deflectometry (CPD) method for measuring solar concentrating mirror panels....
Solar concentrators for advanced solar-dynamic power systems in space...performed by Hughes Danbury Optical Systems, HDOS, (formerly Perkin-Elmer) to design, fabricate, and test a lightweight (2 kg/sq M), self supporting, and highly reflective sub-scale concentrating mirror panel suitable for use in space....
Optimal heat collection element shapes for parabolic trough concentrators... It is shown in this article that the optimal shape, assuming a perfect parabolic figure for the concentrating mirror, is instead oblong, and is approximately given by a pair of facing parabolic segments
