FROM THE ARCHIVE / 1948

Before the spectacle: holography’s wavefront problem

The 1948 and 1962 papers explain why the technical meaning still matters.

A microscopy origin

Dennis Gabor’s A New Microscopic Principle appeared in Nature in May 1948. The paper begins with an electron-microscopy problem, including the effect of spherical aberration. That is a useful correction to a history told only through concerts and advertising. The original technical ambition was to record information about a wave and use it in reconstructing an image.

The month is retained here because publication metadata and issue dating should not be collapsed into a fabricated event timestamp. This page is a retrospective prepared in September 2026; Presence Atlas is not claiming to have reported the work in 1948.

Reconstruction is the distinction

Leith and Upatnieks’ 1962 paper, Reconstructed Wavefronts and Communication Theory, discusses recording a Fresnel diffraction pattern and using that record to construct an image. It also addresses reconstruction and noise limitations. This is a technical lineage, not a catalogue of everything now sold as a hologram.

A photograph, a stereo pair and a holographic record can all represent a three-dimensional subject while carrying different information. When evaluating a display, ask which information is produced and how it reaches the eye. That question can separate an optical mechanism from the promotional vocabulary around it.

Use the history as a buying question

The practical value of this history is a more precise request. Ask a supplier whether the system reconstructs a wavefront, emits light through a volume, sends multiple views from a panel or presents a reflected video image. Then ask what each choice means for the audience and the room.

Do not use historical prestige as a quality score. A reflection can be an excellent stage device, and a sophisticated wavefront method can still be unsuitable for a large shared audience. The relevant comparison is between the experience you need and the constraints the mechanism imposes. The historical papers help name the categories; a present-day demonstration must establish fitness for your project.
