Phase Hologram by Acoustic Metasurfaces
Small Structures, Volume 7, Issue 3, March 2026.This work has achieved a breakthrough in holographic communication, realizing phase holographic imaging. The proposed phase holographic concept overcomes the limitations of traditional amplitude holographic energy attenuation. The design of its amplitude compensation method further addresses the key challenge of phase holographic imaging clarity ...

Attributing scientific and technical progress: the case of holography [PDF]
, 2005 Holography, the three-dimensional imaging technology, was portrayed widely as a paradigm of progress during its decade of explosive expansion 1964–73, and during its subsequent consolidation for commercial and artistic uses up to the mid 1980s.

Data extrapolation method for near-field acoustic holography
Journal of the Acoustical Society of Japan (E), 1998 We propose a new data smoothing method for near-field acoustic holography (NAH) with the aid of the data extrapolation. This method can reduce the error energy which comes from the finiteness of the measurement aperture. We illustrate our calculational results by using of the computer simulations which apply to the numerically generated data by Fast ...

A Comparison of Near-Field Acoustical Holography Methods Applied to Noise Source Identification [PDF]
, 2019 Near-Field Acoustical Holography (NAH) is an inverse process in which sound pressure measurements made in the near-field of an unknown sound source are used to reconstruct the sound field so that source distributions can be clearly identified.
