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

open access: yesHuli 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.

Bayesian Optimization of Grayscale Patterns for Layer‐Height Accuracy in Projection Multi‐Photon 3D Printing

open access: yesLaser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
Bayesian optimization combined with in situ quantitative phase imaging enables autonomous correction of layer‐height deviations in projection multi‐photon lithography. By jointly tuning model parameters and grayscale exposure settings, the method achieves more uniform and accurate layers within 300 prints, offering a fast, data‐efficient route to ...

Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography

open access: yesLaser &Photonics Reviews, Volume 20, Issue 17, 3 September 2026.
By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

What can be achieved with holography? [PDF]

open access: yes, 2016
“Holography by itself is a somewhat narrow field, but combine it with others and it makes an area big enough to spend a lifetime in,” stated Emmett Leith (1927-2005), the “reinventor” of the holographic process and co-inventor of the 3-D hologram. Proof

Nested holography

open access: yesPhysical Review D
Recently, we introduced a symmetry on the structure of angular momentum that interchanges internal and external degrees of freedom. The spin-orbit duality is a holographic map that projects a massive theory in four-dimensional flat spacetime onto the three-dimensional

Planar Super‐Oscillation Diffractive Lenses: Practical Developments and Applications

open access: yesNanophotonics, Volume 15, Issue 16, 26 August 2026.
This review examines planar super‐oscillation diffractive lenses as a unified framework for super‐oscillatory lenses and supercritical lenses. It focuses on applications in super‐resolution imaging, micro/nanofabrication, and precision measurement and relates their application‐specific requirements to focal‐field control, multiobjective design ...

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

open access: yesJixie 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.
