Merry Christmas!

Hi John

I'm a little late with a reply, but I hope that you and your family had a pleasant Christmas.

May I take this opportunity to now wish everyone a happy, healthy and peaceful 2014.

Cheers

Well, I will send for you 3 lamps with holograms, I will put more other holograms, it can compensate for part of your expenses. But today I do not have time to send.
Only I can tomorrow.
Good luck

Lamp + hologram

Anyone Shooting Holograms Out There?

Just moving over from old Agfa 8E75HD film to VRP-M film. I'm currently using the Agfa which is red sensitive with a 532nm green laser. This means longer exposures (something i'm trying to get away from), hence the move to VRP-M which is specifically for green light. I've had a few samples of this f...

(I also read about the litiholo kit but I am not interested, because apparently you can’t make white-light-visible holograms with that one, which is something I want to do. Also, I simply don’t trust this self-developing chemistry.). Yes, you can make white light reflection holograms with the Litih...

new user- wind tunnel

Or is he(?) wanting to use 'real time' interferometry to see the stress patterns on objects in the tunnel? Have I got the correct terminology there?, i've seen it done with a 'wing' as wind speed increases you can see the stress points. Similar to cross polarisation, but different ;). If I knew what...

Gantry for making H1 and H2 Holograms

Certainly looks impressive John. Have you been able to test it out properly yet?

We could do to have a 'catch up', i'm bogged down with work this week, but hopefully the weekend will bring some respite... Skype???

Cheers
