Abstract:
1. An active optical beam shaping system, comprising: a first deformable mirror arranged to at least partially intercept an entrance beam of light and to provide a first reflected beam of light; a second deformable mirror arranged to at least partially intercept said first reflected beam of light from said first deformable mirror and to provide a second reflected beam of light; and a signal processing and control system configured to communicate with said first and second deformable mirrors, wherein said signal processing and control system is configured to provide control signals to said first deformable mirror so as to configure a reflecting surface of said first deformable mirror to substantially conform to a calculated surface shape, wherein said signal processing and control system is further configured to provide control signals to said second deformable mirror to configure a reflecting surface of said second deformable mirror to substantially conform to a calculated surface shape, wherein said first deformable mirror, said second deformable mirror and said signal processing and control system together provide a large amplitude light modulation range to provide an actively shaped optical beam, wherein said large amplitude modulation range is characterized by wherein is a focal gradient of at least one of said first deformable mirror and said second deformable mirror at a point of a respective reflecting surface thereof, wherein h is a surface deflection of a corresponding one of said first deformable mirror and said second deformable mirror at said point, and wherein θ
