The instant invention is concerned with method and apparatus for induced dipole alignment of solar concentrator micro-mirrors. Novel method and apparatus are taught for coupling to, addressing, and alignment of a micro-optics solar concentrator system for single-axis and two-axis tracking. Mirrored micro-balls are covered with a thin spherical shell of lubricating liquid so that they are free to rotate in an almost frictionless encapsulation in the sheet. Novel method and apparatus are presented for matching the overall ball density with that of the lubricating fluid. Broadly this invention deals with novel concepts used for alignment in the focussing of light wherever mirrors are used for focussing such as for solar propulsion assist, illumination and projection of light, optical switching, etc. A particularly important objective is the focussing of sunlight for solar power conversion and production.
