Thank you, Sunny Bains, for putting HOLOGRAPHICS INTERNATIONAL online! These “old” issues provide an incredible wealth of information!

Thank you indeed, Sunny. Brings back so many memories.

Now let's see if we can get Holosphere online too...

wow fantastic to see these! thankyou!

if the Holosphere was online that would be a double headder!

Thanks for posting that, Martin.

Among other interesting things, I saw Kaveh's "Fringe Locking Preview" from the winter '88 issue. It's about a fringe-locking method which promises to be better than any of the others, although it does require a material that shows some real-time effects, like DCG (it won't work with silver). There is a comprehensive and up-to-date discussion of this method by Lucila Cescato and Jaime Frejlich in a book called Three-Dimensional Holographic Imaging, edited by Kuo/Tsai (2002).

I think this method has tremendous potential for display DCG, because the actual real-time fringes in the newly-forming hologram (which create a moire pattern) are the things being locked onto. There is no secondary interferometer or secondary hologram involved. Thus, it promises to be the most "direct" of all fringe-locking techniques.

I have quite a few papers by the Frejlich group dating between '86 and '02. But as of yet, I haven't done any tests, nor do I know of a single person who has reported successful results with DCG.

Martin,

Thanks for the links.

Very interesting material!

WOW - a HeNe that produces 25mW SLM way back in 1987...how cool!

You know, I can't even remember writing that. But if noone steps forward, I'll take the credit.
