  • Signal Recovery and Synthesis (SRS) 2005 paper: JMA1
  • Technical Digest
  • Fienup, James R
  • One can decrease the complexity of imaging optics by increasing the demands on the illumination system or on post-detection computations. A lens-less coherent imaging system...

  • Signal Recovery and Synthesis (SRS) 2005 paper: JMA2
  • Technical Digest
  • Gustafsson, Mats
  • Microscope resolution can be extended through structured illumination followed by linear data processing. The possible resolution increase, determined by the highest spatial...

  • Signal Recovery and Synthesis (SRS) 2005 paper: JMA3
  • Technical Digest
  • Schwartz, Chaim; Dogariu, Aristide
  • Optical fields containing phase singularities provide additional capabilities in studying random media. Coherent backscattering of such fields will be thoroughly discussed for the...

  • Signal Recovery and Synthesis (SRS) 2005 paper: JMA4
  • Technical Digest
  • Pitsianis, Nikos P; Brady, David J; Sun, Xiaobai
  • We introduce a compressive encoding at the sensor layer based on the quantized cosine transform. Compression at the physical layer of integrated imaging systems reduces the...

  • Technical Digest
  • Green, Joseph J; Niessner, Albert F; Shaklan, Stuart B
  • We present an efficient wavefront sensing approach for coronagraphic imaging systems. By measuring the pupil intensity after a coronagraph while known phase errors are injected, the...

  • Technical Digest
  • Vogel, Curt
  • We review preconditioned conjugate gradient approaches for the robust, efficient solution of large linear systems of equations that arise in wavefront reconstruction for extremely...

  • Signal Recovery and Synthesis (SRS) 2005 paper: JTuB3
  • Technical Digest
  • Give'on, Amir; Kasdin, Jeremy N; Vanderbei, Robert J
  • Phase conjugation does not achieve the dark nulls needed for high-contrast imaging. We present an alternative optimized solution for the shaping of the deformable mirror based on the...

  • Signal Recovery and Synthesis (SRS) 2005 paper: JTuB4
  • Technical Digest
  • Seldin, John H; Paxman, Richard G
  • We present the problem of jointly estimating wavefront amplitude and phase from phase-diversity data and provide simulation examples.

  • Signal Recovery and Synthesis (SRS) 2005 paper: JTuC1
  • Technical Digest
  • Christou, Julian C
  • Adaptive optics images of the human retina can be improved using wavefront derived point spread functions (PSF). Errors in these PSFs call for wavefront sensing constraints to be...

  • Technical Digest
  • Pugliese, Giovanna; Bonaccini Calia, Domenico; De Marchi, Guido; Paresce, Francesco
  • We address the problem of astrometry and photometry in presence of anisoplanatism in very crowded fields with adaptive optics data. We present a data reduction technique that...

  • Signal Recovery and Synthesis (SRS) 2005 paper: JTuC4
  • Technical Digest
  • Aubailly, Mathieu; Roggemann, Michael C
  • AO systems are effective for narrow field of view. We propose a post-processing method to reduce the effects of anisoplanatism in wide FOV AO images. The off-axis point-spread...

  • Signal Recovery and Synthesis (SRS) 2005 paper: SMA1
  • Technical Digest
  • Fiddy, Michael A; Kanaev, Andrey; Shahid, Umer; Testorf, Markus
  • A nonlinear filtering technique for inverse scattering is applied to the structure synthesis problem. The method is used with data from known structures to modify their scattering...

  • Technical Digest
  • Boverman, Gregory; Miller, Eric L; Boas, David A
  • We reconstruct polar three-dimensional shapes in Diffuse Optical Tomography using a basis of spherical harmonics. We also show how to efficiently compute the derivative of our...

  • Technical Digest
  • Millane, Rick P; Yoon, Chun Hong; Bones, Philip J
  • Location of myosin filaments in electron micrographs of muscle cross-sections is difficult because of contrast variations and noise. Two algorithms that incorporate a priori...
