What Advanced Holography Topics Are Covered on HoloWiki?

Updated

HoloWiki's advanced section covers four main areas: holography safety, holography technology (hardware and setups), hologram recording materials (including chemistry), and holography theory (the mathematics and science behind holography). It also provides two reference tools — a glossary of technical terms and a list of common abbreviations — to help you read the rest of the material. This is aimed at people who already make holograms and want to go deeper, not at complete beginners.

The advanced topics, at a glance

Topic What it covers
Holography Safety Chemical and laser safety. The site flags this as "a must read!"
Holography Technology The hardware and setups used for making holograms
Hologram Recording Materials How to get, make, and use recording materials, plus the associated chemistry
Holography Theory The mathematics and science of holography
Holography Glossary Technical terms defined
Abbreviations Commonly used abbreviations among holographers

How these fit together

The four subject pages are not independent. If you are working on a practical problem, you will usually move between them:

  • Safety first. Before handling chemicals or running a laser, read Holography Safety. It is the one page the site explicitly marks as required reading.
  • Technology → Materials → Theory. Holography Technology tells you what hardware and setups are used. Hologram Recording Materials tells you how to obtain, prepare, and process the recording medium, including the chemistry. Holography Theory explains why the setup and the material behave the way they do.
  • Glossary and Abbreviations as you go. Technical terms and shorthand appear throughout the advanced pages. Keep the glossary and abbreviation list open as reference rather than reading them start to finish.

Related advanced material elsewhere on the site

The main page also points to advanced-adjacent resources that sit outside the four core topics:

  • Experimenter's Corner — odd things to try, or what others have already tried.
  • Hints and Kinks — tips and techniques shared by other holographers.
  • Equipment and Homemade Equipment — gear used in making holograms, some of which is easily built at home.
  • History of Dichromate Holography — a timeline of people and technology in dichromated gelatin holography, which pairs with the DCG material in the basic section.
  • Recent additions include a DCG color tuning guide derived from the Holography Forum archives, a compilation of chemistry for holographic developers and bleaches (courtesy of Ed Wesly), and a cold water processing article by Ed Wesly.

Who this section is for

The advanced pages assume you already have a footing in holography. If you are just starting, the site's own structure points you to the Beginner's Corner and the Dichromated Gelatin basics first. Once you are making holograms and want to branch into DCG, tune color, mix your own developers and bleaches, or understand the underlying theory, the advanced section is where you go.

One practical note: the site describes itself as a wiki and FAQ maintained by the Holography Forum community, with John Fisher as site administrator. Content is contributed and updated over time, so specific pages — especially the chemistry compilations and recent additions — are worth checking for the latest version rather than assuming a fixed text.
