    • Compressive holography of diffuse objects. 

      Choi, Kerkil; Horisaki, Ryoichi; Hahn, Joonku; Lim, Sehoon; Marks, Daniel L; Schulz, Timothy J; Brady, David J (Appl Opt, 2010-12-01)
      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. 

      Horisaki, Ryoichi; Choi, Kerkil; Hahn, Joonku; Tanida, Jun; Brady, David J (Opt Express, 2010-08-30)
      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 J; Oliver, Tim (Appl Opt, 2010-04-01)
      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 L; Choi, Kerkil; Horisaki, Ryoichi; Brady, David J (Opt Lett, 2010-03-15)
      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. 

      Xu, Qian; Shi, Kebin; Li, Haifeng; Choi, Kerkil; Horisaki, Ryoichi; Brady, David; Psaltis, Demetri; ... (8 authors) (Opt Express, 2010-04-12)
      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 wave ...
