  • Two mirror system
    Patent number: 8894226
    Abstract: A method for producing a multiple surface system that may be a two-mirror surface. The method involves first finding from a given primary curve an appropriate secondary curve. The method then uses ideas from exterior differential systems to grow from the primary curve and the secondary curve, primary and secondary mirror surfaces. The Cartan-Kähler theorem gives a strong indication of the existence of such solution surfaces.
    Type: Grant
