The easiest would be to try recording a small Denisyuk hologram, with beam spread to a small area, say diameter 3 cm. That should make irradiance strong enough.

Yes, "chrome bleach" is a potassium dichromate bleach. Overexposure generally leads to lower contrast of fringes - parts of the emulsion that were intended to be "unexposed" get some exposure due to excess time, while the parts that were intended to be "fully exposed" a...

One more thing to consider: photopolymer requires at least threshold irradiance [mW/cm2] in order to record anything. If yoour diode is weak, making the exposure longer does not help. (Contrary to silver halide, where you can usually compensate weak laser by longer exposure.) I did not test HX200 at...

Would you expect JD-2 holograms to reconstruct in green? Yes. The green shift is caused by shrinkage of the emulsion. The fringes recorded in the volume of the emulsion act as mirrors (not exactly, but it is a useful model). The distance between the mirrors is determined by the wavelength used in t...

I guess it should be arranged to satisfy the majority and perhaps the organizer.

Surprisingly bright! I wonder where the color came from. Did you alter JD-4 processing? Normally, PFG-03M processed with JD-4 reconstruct in red.

It would be great!

Hi, Dan,
it seems you are not completely sure if the problem is in DCG or somewhere else. I think it would be worth buying a pack of photopolymer (e.g. from Geola or Litiholo) and test the setup with it.

Welcome, Julian.
Your paper looks interesting. Maybe I finally get an answer what is the Mellin transform good for

Chimera process has nothing to do with CGH as discussed in this thread - as far as I know. The Chimera printer is just an evolution step in a well-known holographic stereogram production, the same as Geola, Zebra Imaging, XYZ, former Ultimate printers, etc. The construction is well described in, e.g...
