Optics Letters, 1985 A new method for recording holograms using incoherent light is described. The method is based on optical propagation through birefringent crystals. Optical methods for the reconstruction of such a hologram are also presented.

Intrinsic speckle noise in in-line particle holography due to poly-disperse and continuous particle sizes [PDF]
, 2000 In-line particle holography is subject to image deterioration due to intrinsic speckle noise. The resulting reduction in the signal to noise ratio (SNR) of the replayed image can become critical for applications such as holographic particle velocimetry ...

International Journal of Modern Physics D, 2003 An elementary introduction to Maldacena's AdS/CFT correspondence is given, with some emphasis in the Fefferman–Graham construction. This is based on lectures given by one of us (E.A.) at the Universidad Autonoma de Madrid.

ACM Transactions on Graphics, 2023 Holographic displays promise several benefits including high quality 3D imagery, accurate accommodation cues, and compact form-factors. However, holography relies on coherent illumination which can create undesirable speckle noise in the final image. Although smooth phase holograms can be speckle-free, their non-uniform eyebox makes them impractical ...

Recent Advances in Imaging of Light Propagation with Light-in-Flight Recording by Holography
Ultrafast Science, 2023 In the last few decades, there have been several advances in ultrafast imaging of light propagation with light-in-flight recording by holography (LIF holography), which can capture light propagation as a motion picture with a single shot in principle ...

An exact construction of codimension two holography
Journal of High Energy Physics, 2021 Recently, a codimension two holography called wedge holography is proposed as a generalization of AdS/CFT. It is conjectured that a gravitational theory in d + 1 dimensional wedge spacetime is dual to a d − 1 dimensional CFT on the corner of the wedge ...
