Strong Coupling Holography

, 2009
We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4+d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong

Single to multiple digital holograms for phase compensation and defect detection

Frontiers in Photonics
Digital holography enables quantitative phase imaging based on interference. A digital hologram often encodes the phase information along with aberrations or deformations.

Portable Filter-Free Lens-Free Incoherent Digital Holography System

Photonics
A portable incoherent digital holography system without a polarization filter or a refractive lens was developed. Phase-shifted self-interference incoherent holograms of light diffracted from an object were generated without attenuation due to a ...

Observation on Use of Holography External Treatment to Relieve Pain in Post-operation Patients With Anal Diseases

Huli yanjiu, 2000
In view of post-operation pain in patients with anus diseases, holography treatment was used. Effects were observed and compared it with those patients relieved pain by taking analgesic orally.

METHOD FOR PLANE NEAR-FIELD ACOUSTIC HOLOGRAPHY BASED ON COMPRESSIVE SAMPLING AND ITS APPLICATION

Jixie qiangdu, 2016
In traditional plane near-field acoustic holography reconstruction process,regardless of wave number domain filter or regularization method,they cannot solve their own ill-posed problem,and thus cannot improve the reconstruction accuracy.
