  • Adaptive optics systems using pixilated microelectromechanical systems (MEMS)
    Patent number: 8254014
    Abstract: An adaptive optics system is provided, comprising a spatial light modulator configured to modulate an incoming beam with an aberrated wavefront, a beamsplitter configured to receive the modulated beam from the spatial light modulator and to divide the modulated beam into a measurement beam and a reference beam, a spatial filter configured to spatially filter the reference beam, and to interfere the spatially filtered reference beam with the measurement beam to form an interferogram, an imaging device configured to capture an image of the interferogram, and a processor configured to determine the aberrated wavefront and to provide control signals to the spatial light modulator to mitigate aberrations in the aberrated wavefront.
    Type: Grant
    Filed: June 16, 2010
