ISDH and the CHIMERA™ Hologram Contest

The International Symposium on Display Holography (ISDH) was postponed due to COVID-19 but, as Philippe Gentet of the Hologram Forum announced at the Holography Conference Online last month, the 12th ISDN is now scheduled to take place at the Ambassador Seoul, Korea, from 26 June to 1 July 2023.

The first ISDH was convened by Professor Tung H Jeong in 1982 at Lake Forest College in Illinois, USA. The aim of ISDH is to synthesise history, education, art, science and economic developments that involve holography. It is organised by Kwangwoon University and the Hologram Forum, which includes over 20 organisations and was established to create a hologram business ecosystem between companies, universities, research institutes and the Korean government.

Within the framework of the ISDH2023 conference, a hologram contest will be run by the Hologram Forum in collaboration with Yves Gentet (Ultimate Holography) and Kwangwoon University to find the best projects submitted using the CHIMERA™ recording technique. CHIMERA is a digital holographic printing system jointly developed by Ultimate Holography and Kwangwoon University.

How to create a CHIMERA

In the CHIMERA printer, three low power continuous wave RGB lasers, with wavelengths of 640, 532 and 460 nm, are used to deliver good colour balanced images with full parallax across a 120 degree field of view. The hogel size of 250 μm results in a display that, to the human eye, appears seamless.

The CHIMERA print is first created by recording a series of 768 horizontal images – points of view of the scene – on a 120-degree arc of a circle for a half- parallax hologram. A full-parallax display keeps the same requirements, but the procedure is repeated at 178 levels of elevation, creating a cylinder of points of view.

A CHIMERA can be created with a 3D model and a virtual camera in a 3D computer graphics programme like 3ds Max and Unreal Engine or a physical model and a camera.

Contest details

The project can be realised using a 3D model or from a real model. The final CHIMERA hologram will be recorded with dimensions of 30x40 cm, with a hogel resolution of 250 μm and can be either full or half parallax.

The 10 best projects will be recorded and exhibited during the conference and an official jury will award the prize for best hologram. There will also be a prize to be voted on by the participants of the conference.

The contest organisers say they are expecting new, innovative, artistic, and technical projects... but above all surprising ones.
