    • Compressive holography. 

      Brady, DJ; Choi, K; Marks, DL; Horisaki, R; Lim, S (Opt Express, 2009-07-20)
      Compressive sampling enables signal reconstruction using less than one measurement per reconstructed signal value. Compressive measurement is particularly useful in generating multidimensional images from lower dimensional ...
    • Dynamic Metasurface Apertures for Computational Imaging 

      Sleasman, Timothy (2018)
      Microwave imaging platforms conventionally take the form of antenna arrays or synthetic apertures. Inspired by methods in the optical regime, computational microwave imaging has recently taken hold as an alternative approach ...
    • Nanophotonics: Optical time reversal with graphene 

      Ciracì, Dr Cristian; Smith, David R; Urzhumov, Yaroslav A (2013-07)
      Would you ever guess that a microscopic flake of graphite could reverse the diffraction of light? An experiment that demonstrates just such an effect highlights the exciting optical applications of graphene — an atomic layer ...
    • Parallel on-axis holographic phase microscopy of biological cells and unicellular microorganism dynamics. 

      Ehlers, MD; Newpher, Thomas Mark; Shaked, NT; Wax, A (Appl Opt, 2010-05-20)
      We apply a wide-field quantitative phase microscopy technique based on parallel two-step phase-shifting on-axis interferometry to visualize live biological cells and microorganism dynamics. The parallel on-axis holographic ...
