    • High Time Resolution Astrophysics in the Extremely Large Telescope Era : White Paper 

      Shearer, Andrew (2010)
      High Time Resolution Astrophysics (HTRA) concerns itself with observations on short scales normally defined as being lower than the conventional read-out time of a CCD. As such it is concerned with condensed objects such ...
    • High-resolution, wide-field object reconstruction with synthetic aperture Fourier holographic optical microscopy 

      Hillman, Timothy R.; Gutzler, Thomas; Alexandrov, Sergey; Sampson, David (Optica, 2009)
