Four-dimensional dynamic flow measurement by holographic particle image velocimetry [PDF]

open access: yes, 2005
The ultimate goal of holographic particle image velocimetry (HPIV) is to provide space- and time-resolved measurement of complex flows. Recent new understanding of holographic imaging of small particles, pertaining to intrinsic aberration and noise in ...

Photon counting compressive depth mapping [PDF]

open access: yes, 2013
We demonstrate a compressed sensing, photon counting lidar system based on the single-pixel camera. Our technique recovers both depth and intensity maps from a single under-sampled set of incoherent, linear projections of a scene of interest at ultra-low

Three-dimensional imaging of dislocations [PDF]

open access: yesNature, 2013
arising from C.-C. Chen et al. , 74–77 (2013)10.1038/nature12009 At first sight, the achievement of determining atom positions in three dimensions appears spectacular1. Chen and colleagues1 apply a form of tomographic reconstruction to a tilt series of annular dark field (ADF) images of crystalline ...

Differential Photoelectron Holography: A New Approach for Three-Dimensional Atomic Imaging

open access: yes, 2003
We propose differential holography as a method to overcome the long-standing forward-scattering problem in photoelectron holography and related techniques for the three-dimensional imaging of atoms.
