Have the 2015 ISDH Proceedings been published? I'd like to get a copy.

Anybody planning on doing the St. John festival in Porto before the ISDH?

June 2018 isn't very far away. Come on, some of you want to go - right?
Just get on Travelocity and go!

I have a better idea. Come to ISDH 2018 to see.

It's in Portugal. Who's going?

I just found an unopened box of PFG-03C plates with a production date of April 2004 and some Agfa 8E75 NAH from June 1995. Any bets if this stuff is still any good?

I use Toslink (or generic equivalent) optical cables. They are cheap 1 mm diameter multi mode fibers used for linking audio, TV, DVD, etc entertainment components together. Just shoot your laser beam into one end and use what comes out the other end for the reference beam. If needed, you can use a c...

I wish too. Mine looks like most of the emulsion washed away.

Thanks for the reply. What I'm trying to measure is the residual spatial coherence of a beam after passing thru different lengths of multimode fibers. With a C315M I've made holograms using the up to 50 foot long multimode fibers for both the reference and the object so I know there is some coherenc...
