Abstract: A described embodiment provides a technology for concentrating or focusing electromagnetic energy to an arbitrary desired spatial distribution, utilizing a rotatable base, a plurality of mirrors mounted to the rotatable base, and an optical receiver that is moveable in an azimuth path relative to the plurality of mirrors. A described embodiment can comprise a driver for rotating the base and a adjusting linkage that connects the plurality of mirrors so that they track in a coordinated fashion. Another embodiment comprises an optical positioning assembly on which each mirror is mounted. An optical positioning assembly adjusts each mirror to the sun's altitude and the location for the optical receiver. This assembly is connected to the adjusting linkage so that a single driver can move all the mirrors if desired.
