  • OSA Technical Digest (CD)
  • Zhariy, Mariya
  • We present a wavefront reconstructor for the Shack-Hartmann wavefront sensor with linear complexity. This algorithm allows for a simple adaptation to the aperture geometry. We derive...

  • Signal Recovery and Synthesis (SRS) 2011 paper: JTuA5
  • OSA Technical Digest (CD)

  • OSA Technical Digest (CD)
  • Restrepo, Alejandro; Lopez, Francisco
  • This paper presents preliminary studies of RGB and HSV color spaces analysis for polarized light images of plastic films under tensile deformation. The results obtained show a tool for...

  • Signal Recovery and Synthesis (SRS) 2011 paper: JTuC1
  • OSA Technical Digest (CD)
  • Thiébaut, Eric
  • Inverse problem approach is a suitable framework to analyze the issues in image reconstruction from interferometric data. It can be exploited to describe and formally compare the new...

  • Signal Recovery and Synthesis (SRS) 2011 paper: JTuC2
  • OSA Technical Digest (CD)
  • Meitav, Nizan; Ribak, Erez N
  • We take advantage of ocular saccades to average out some of the high order aberrations. Combining a long sequence of oversampled retinal images we were able to resolve single cells...

  • Signal Recovery and Synthesis (SRS) 2011 paper: JTuC3
  • OSA Technical Digest (CD)
  • Meitav, Nizan; Ribak, Erez N
  • We developed two automated methods for measuring the hexagon size and the fraction of hexagonally packed cones. Density is mostly set by adjacent cones, decreasing with eccentricity....

  • Signal Recovery and Synthesis (SRS) 2011 paper: JTuC4
  • OSA Technical Digest (CD)
  • Wirth, Allan; Gonsalves, Robert; Jankevics, Andrew
  • Phase diversity has proven a viable technique for wavefront sensing but converges too slowly for real-time applications. The small wavefront changes in a closed loop system allow much...

  • Signal Recovery and Synthesis (SRS) 2011 paper: JTuC5
  • OSA Technical Digest (CD)
  • Korkiakoski, Visa; Keller, Christoph; Doelman, Niek; Fraanje, Rufus; Verhaegen, Michel
  • We demonstrate the potential of joint-optimization of adaptive optics (AO) and phase-diversity (PD). The wavefront sensor information reduces computational costs by a factor of 20, and...

  • OSA Technical Digest (CD)
  • Redman, Stephen; Lawler, James E; Nave, Gillian; Ramsey, Lawrence; Mahadevan, Suvrath
  • Precise calibrations are needed for high-resolution near-infrared astronomical spectrographs. We have measured the wavenumbers of over 7500 uranium emission lines and used a subset of...

  • Signal Recovery and Synthesis (SRS) 2011 paper: JWA10
  • OSA Technical Digest (CD)
  • Gladysz, Szymon; Ribak, Erez N
  • We use a Wynne corrector to radially disperse images of exoplanets while shortening the stellar speckles. This results in a morphological difference between speckles and sources...

  • Signal Recovery and Synthesis (SRS) 2011 paper: JWA11
  • OSA Technical Digest (CD)
  • Boudebs, Georges
  • We report on third order optical nonlinear experimental characterization through focal shift measurements. The focus in the nonlinear regime is related to the nonlinear phase shift....
