After several days of tests I’ve gotten a couple of decent transmission holograms on VRP-M using a Coherent 315m.

Back in the lab
You ever look back at something you did months ago and wonder, "why did I do that?"
I did that this evening with the controller that I’ve got in my lab.
I’m starting work on another hologram for a professor at A&M and needed to do a bit of maintenance on the table. Strange, but every time a new hologram request from her comes in, there’s something that needs doing in the lab before I can get started.
This time the HEPA fan wasn’t shutting off during an exposure and the table light sensor wasn’t working.
It turned out with the HEPA fan that somehow I’d wired up the relay connection with an additional 5v going to it. I have no idea why I did that. Fortunately it just caused the controller chip on that port to heat up (and not work) but didn’t blow anything. Odd that it was working for a while and then just stopped.
The light sensor just turned out to be a loose connection at the junction between the table wiring and the controller wiring. Gremlins.
I also found a problem with the holocontroller software not always shutting off the fan and fixed that.
Now I just need to straighten up the lab, prep some film, paint the subject and shoot. All tomorrow morning.
Holograms by Lon Moore in the store
I’ve added 10 of Lon Moore’s photopolymer holograms to the store which are available for immediate purchase. These holograms were originally created for his Red Beam line and several have become collectible items.
The holograms include:
Saturn
The original Enterprise from Star Trek
Dracula
Among others.
The making of “Friends”
For the latest Holography Forum contest I made a hologram of Snoopy and Woodstock.
I’d originally planned for the final hologram to be a bit different but I’m happy with what I’ve got.
Read on for the making of Friends.
Facia
Here’s my latest hologram, a two-color 4×6" reflection hologram of multi-dimensional faces.

You can also purchase a framed copy through our store.
Two-color 4th of July
Late last week I put together a shot of the fireworks from my original 4th of July hologram and the latest version of the flag into a two-color version that I’ll be selling as a limited edition of 100.
Day of the Dead
A few weeks ago I started work on a hologram inpired by Pirates of the Caribbean and began carving a medallion that I wanted to look like the medallion featured in the movie. Unfortunately my sculpting skills aren’t yet up to that task but I was able to produce a medallion that is more appropriate for a Day of the Dead celebration and set about making a hologram of that.
Sand Dollar two channel
Back on June 5th I wrote about some problems producing a master two channel of a sand dollar. I’ve since worked out the problems and made a few copies.
4th of July
The big project this week was a new version of the US flag hologram I made for Andres when he became a US citizen.
I’ve wanted to add fireworks for some time now and started work on just that last weekend.
Photographing reflection Holograms
Getting a good photograph of a hologram isn’t always an easy proposition but if you use the right tools and are patient you can get excellent results just about every time.
This tutorial assumes you have full control of the hologram and can take it off the wall at will. If you’re trying to take a picture of a hologram that’s permanently mounted to a wall or one where the owner won’t allow you to move it, you’ll need to adjust accordingly.
