  • Compressive holography of diffuse objects
    Choi, Kerkil; Hahn, Joonku; Lim, Sehoon; Marks, Daniel; Brady, David (OPTICAL SOC AMER, 2010)
    We propose an estimation-theoretic approach to the inference of an incoherent 3D scattering density from 2D scattered speckle field measurements. The object density is derived from the covariance of the speckle field. The ...
  • Generalized sampling using a compound-eye imaging system for multi-dimensional object acquisition
    Choi, Kerkil; Hahn, Joonku; Brady, David (OPTICAL SOC AMER, 2010)
    In this paper, we propose generalized sampling approaches for measuring a multi-dimensional object using a compact compound-eye imaging system called thin observation module by bound optics (TOMBO). This paper shows the ...
  • Identification of fluorescent beads using a coded aperture snapshot spectral imager
    Cull, Christy Fernandez; Choi, Kerkil; Brady, David (OPTICAL SOC AMER, 2010)
    We apply a coded aperture snapshot spectral imager (CASSI) to fluorescence microscopy. CASSI records a two-dimensional (2D) spectrally filtered projection of a three-dimensional (3D) spectral data cube. We minimize a convex ...
  • Imaging through turbulence using compressive coherence sensing
    Wagadarikar, Ashwin A.; Marks, Daniel; Choi, Kerkil; Horisaki, Ryoichi; Brady, David (OPTICAL SOC AMER, 2010)
    Previous studies have shown that the isoplanatic distortion due to turbulence and the image of a remote object may be jointly estimated from the 4D mutual intensity across an aperture. This Letter shows that decompressive ...
  • Inline holographic coherent anti-Stokes Raman microscopy
    Choi, Kerkil; Horisaki, Ryoichi; Brady, David (OPTICAL SOC AMER, 2010)
    We demonstrate a simple approach for inline holographic coherent anti-Stokes Raman scattering (CARS) microscopy, in which a layer of uniform nonlinear medium is placed in front of a specimen to be imaged. The reference ...
