Want a photopolymer that works?

Over the weekend I had the time to start testing the latest batch of photopolymer from Polygrama and I have to tell you that it was a pleasure to work with. But let me back up a bit and take you to the beginning of the testing session.

Laminating Film to Glass

The subject of what to do instead of index matching film to glass comes up periodically so it was again time to write up a tutorial. Continue reading “Laminating Film to Glass”

HoloController update

If anyone’s interested in checking out the first fully functional (although as far as the final version goes, proof of concept) version of HoloController, I’ve just made a source and executable release through sourceforge.

http://sourceforge.net/projects/holocontroller/

I’m looking for feature ideas as well as people to contribute to the software. Check out the roadmap on the home page for more info on what I’ve got planned at the moment.

Squeegeeing

The topic of film squeegeeing comes up fairly regularly on the holography forum and I’ve been meaning to write up a method that I use with good success.

Computer Control for the Table

A few months ago I bought some hardware for interfacing my computer with the outside world along with a relay card and stepper motor card. I had some time over the weekend (actually I just couldn’t put it off any longer) to finish soldering the main board together and hook it up to the computer and table.

Back in November, during the PCGG-II gathering, several people spent a lot of time and effort trying to get a hologram out of the Liti Holographics material. After the gathering I put together a review and sent it off to Liti for comment.

Musings & review

It’s been a while since my last update and I’ve been busy copying various holograms and a few long business trips.

Ok, I’ll admit it, I’ve also been playing Half Life 2. Though not nearly as much as I’d like. Mainly the time when I’d be letting the table settle anyway.

At the moment I’m working on a new version of the PCGG-II hand-off hologram because I’m unhappy with the final results of the original. While elements of it worked well in a transmission, the contrast levels weren’t good for making reflection copies. As soon as I get the chance I’ll post some pictures of my latest work.

In the meantime, check out the Liti review I’ve just posted.
