I suspect you are not really making a hologram, metalstar. How are you using 4 lasers one on each side?

What the hell is going on here:

(Oh OK. Merry xmas)

Sounds like a useful report if you have $5000 to spare.

The answer to your question is no, it is not possible to have the same lateral and longitudinal magnification when scaling an image. This is true whatever optical method you use: Wavelength change, lenses, or change in reconstruction geometry.

I think you might mess up the polarization, no?

From what I recall this is a fundamental problem that has no solution. The speckle will be there whatever you do, as it is caused by the random interference of laser light, and a consequence of the high degree of coherence.

Milan, our thoughts are with you. We have all spent hours in the night in the lab and have had disasters. But we appreciate that holography is still alive, just, only because of the energy that people like you put into it. So we can't fix your laser, but feel your pain at least... Don't give up, dud...

Oh boy... I wish I had not said

Of course color holography is additive by its nature anyway.

in an earlier post.

I think you are right, walschuler. It is exactly the ideas of additive color photography in early 20th century. Of course color holography is additive by its nature anyway. But it is fascinating how holography mirrors early photography, e.g. Lippmann photograpy.

Certainly seems to be a dodgy auto-generated "award". But to be fair to Dinesh, it may be that someone else made the award and Dinesh assumed it was genuine.

Here are similar award winners:
