Abstract:
An apparatus for aligning a solar concentrator having a plurality of facets, said solar concentrator defining a focal point and an optical axis having a vertex, and said apparatus comprising:a first laser for producing a first laser beam for targeting a selected facet of said plurality of facets of said solar concentrator; a target board positioned adjacent to said first laser at approximately one focal length behind said focal point of said solar concentrator such that said target board will be illuminated by said first laser beam from said first laser after reflection of said first laser beam off of said selected facet; and a second laser, located adjacent to said vertex of the optical axis of the concentrator, for producing a second laser beam directed at said target board at a target point thereon such that by adjusting said selected facet to cause said first laser beam to illuminate the target point on the target board produced by the second laser beam, the selected facet can be brought into alignment with said focal point.
