Hello all,
I wonder if I can make a hologram on a normal white paper.
I mean, is it possible that the holographic image will display under strong light?
Thanks alot!

A hologram plate actually has a certain thickness in which it contains a certain "structure" of information. It might seem pretty boneheaded for me to say this, but in order for something to carry non-data optical 3D information, it itself has to be a 3D medium! For this reason, it's not possible to store 3D information with just the 2D printed page, which is what you might be thinking about. If specially prepared paper were to be manufactured, perhaps this might be possible, but for sure it would not be used for "scratch paper". It would cost more.
Addendum: Jon V suggests that one only needs to have intensity and phase to capture 3D information. He is correct. However, there is no way to "record" phase directly, which is why hologram plates function as a 3D diffraction grating. No, you cannot imagine that complex phase could be recorded with something akin to a sound track, that won't work. Oh boy, if only we could do that!

How To Make Holographic Paper

You can't make a holographic plate with a piece of white paper, but if you already have a holographic plate, then you can project the holographic image onto the piece of paper. The piece of paper will also allow you to view the virtual image and the real image, as opposed to just seeing the real image by looking through the holographic plate. I dont think regular daylight or lamp light will be useful in viewing the holograph though. I suggest strong, monochromatic laser light. Good luck

The reason plain paper does not work is that it causes light to lose coherence. You need either a transparent medium or a reflective surface. It is in fact possible to print a hologram on metallic paper.
Also, the medium does not have to be three-dimensional, because holographic information is not truly three-dimensional. Rather, it is two sets of two-dimensional information: the intensity of the light hitting each point on the plate, and its phase at each point on the plate. The phase information is what allows you to reconstruct the distance of the subject from the plate.

Not even. It's the layering that makes it work.
