PCGG-II hand-off hologram

As others are aware, it took way too long to finish (partly because I was being over-ambitious in what I wanted to do and partly because it was an open-ended “artistic” endeavor) but the PCGG-II hand-off hologram is complete and in the Padiyar’s possession.

Welcome our newest US citizen… Andres Ghisays

Today Andres Ghisays (who was born in Columbia) will become a US citizen. He’s off this morning to be sworn in and in honor of this occasion I’ve created a hologram just for him.

Building a holography table with Hexcel

As some already know, this paper took forever to finish but it’s done and ready for the world to read.

If you’ve got any comments or questions just let me know.

Here’s an excerpt from the the introduction:

This paper describes the methods used by myself and Andres Ghisays in building our latest tables as well as a set of recommendations for those considering doing the same.

Hexcel is a honeycomb material often used by the aerospace industry for making structural panels that are very light but extremely stiff or strong. They’re used in aircraft wings, walkways, satellites, Moon-bound spacecraft and can even be found in many cars.

Hexcel honeycomb (hereafter just referred to as "Hexcel") as discussed here is a flat panel made out of aluminum in the shape of a honeycomb.

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”

Backing film with Oracal

I’ve had several people ask me about backing film holograms with Oracal, so here’s a short tutorial.

Latest HoloController update

Over the last many days I’ve been adding to the controller software (sensor logging, light meter readings, etc) and I’ve also begun converting the code to use wxWindows for the app framework and UI.

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.

Read on for more info…

I am fully operational Sir

The board and software now have everything I need (the rest is a bit fluffy) which includes:
1) Software control of both lasers (although I still need to hook the AC relay board to the 33mW laser).
2) Software switches for the lasers and shutters.
3) Basic light sensors that can check to make sure the shutter opened.
4) Status lights for when a laser is on and when an exposure is in-progress (IE, the shutter is open and film is being exposed).

Some shots of the board follow.

Sourceforge project open

The controller software has come far enough along that I’ve opened up a sourceforge account for it and will start accepting other developers that want to help out with the project.

It’s officially open-source at this point and is being released under the GPL license.
