    Default Another Hologram

    Hi all

    I've been working on my holography setup to try and improve a few things. It looks as though my endeavours are finally paying off ...



    This what I've been working towards for the last few years.

    Today is a good holography day :-)

    Very very nice Jem. Bright, great detail. I also like the way you shot the photo with part of your holography equipment in the background. Ron

    Haha... Yes, the holography equipment in the background is my C315m that is currently 'resting'. Also you can just see a bit of my safelight that I use when working with my red HeNe, it's a 20mW JDSU Microgreen

    It's taken me a long time to reach this stage and it's fair to say I'm feeling pretty pleased with myself.

    Credit must also go to John Sonley without whose help I would have still been making single beam Denisyuks

    Well, not quite

    The C315m in the background is an 80mW. I've got 'yours' sitting in a very special box as a spare just in case I ever need another controller .

    Cheers

    and is your microgreen still the one I repaired the controller for?

    nice hologram Jem, it's always great to see homemade ones of such quality

    do you plan on making those holograms which are half inside, half oustide the glass to the eye?

    It sure is

    That's exactly what this one is. The base of the Buddha sticks out in front of the glass by about 25mm, his hands and face are about in the plane of the glass and the rest of him is behind the glass. That's one of the problems when trying to photograph holograms, you don't get a sense of where the image is.

    These types of holograms are known as H2's or image plane holograms, these particular ones reconstruct in white light. It's made not from the original object, but from a transmission hologram 'Master'. This 'Master' hologram when illuminated correctly reconstructs the original image about 12cm in front of itself. A film is then placed into the 'image plane' and exposed resulting in a hologram which spans the glass plate producing both a real and virtual image.

    The problem i've been having is getting sufficient stability to make these H2's as everything needs to be ultra stable to get a decent image.

    Cheers

    Ok, never tried this before. I've just taken a bit of video with my iPhone and uploaded it to Photobucket...

    Be patient, it'll take a couple of minutes to load
