A very interesting subject and certainly relevant to today's environment.
I think that presently, they can be detected with proper equipment, and that capability could be implemented in the recording device (camera) as
well.
There are 3 characteristics that could be a give-away that you are looking at a hologram:
1. highly reflective
2. color changes within a wide range depending on relative position of the light source
3. geometric distortions in stereoscopic 3D imaging, or lack of l/r eye image displacement.
Software exists that can detect a hologram. It is called OpenCV, and is used primarily in print holography, but is adaptable to projection media with
high resolution photography.
We could also use laser devices like lidar to show that the reflected holographic surface has no depth.
It may be detectable with 3d (VR180) optical lenses, that would show no stereoscopic effect when being imaged. That of course, would be if it was only
a flat surface reflectioh. If the projection surface was curved and produced with some projection technique that produces a 3d hologram (like the
Disney and Universal equipment) , It may be really difficult to detect since that produces L/R eye displacement for a stereoscopic effect.
The most important thing is to detect it real-time. It may not be detectable after it is recorded.
I will bet there will be a lot of interest in detecting holograms in the future. Thanks for the thread!
