Fourier-based image sharpness sensor for adaptive optics correction 2009 727 Adaptive optics reduces undesirable turbulence effects present during propagation and imaging through the atmosphere or another random medium. Within an adaptive optics system, wavefront sensing determines the incoming wavefront errors. Image sharpen...
Phase structured wavefields with phase singularities and bispectral properties 2010 1031 The work presented in this dissertation can be subdivided into two parts. The first part illustrates the novel use of a 37 actuator segmented deformable mirror for the creation of optical vortex beams ranging in topological charge from 1 to 10. The...
