Talk:Ghost imaging

Unseen, etc.

Even though popular press is using phrases such as "images that are unseen", this is neither accurate nor explanatory. "Unseen" isn't accurate because light does hit an object and does hit a detector. It just doesn't happen in the same way as camera. Of course, it also doesn't help explain how the technology/science works. Therefore it should be avoided here. Jmattthew (talk) 04:29, 29 March 2014 (UTC)

Quantum Camera is One sensor only, omits second one pixel camera This is different than Quantum Ghost imaging, which it might have been confused with it.

I think the first description of quantum ghost imaging is either at error, or a different published technology is similar but omits the single pixel detector. New Scientist magazine had an article, that nonsentient AI, chatGPT finds at the internet archive WayBack Machine, where a researcher, Shih, utilized quantum entangled photons to image a "figurine", it looked like a human, with (spin?) entangled photons, and a beamsplitter, where with two separate beams, one beam reached and responded to the figurine with quantum (spin?) change, which caused the other beam from the beamsplitter to interact with a photon detector, imaginably a multipixel array chip, to make a computer data image of the figurine. Only one beam interacted with the figurine, and the noisy resolution looked like 1-2mm, but but I really do not know the size of a popsicle stick, so possibly 1-2 mm resolution. Anyone reading this, if this is not "quantum ghost imaging" what is it usually called, thanks. — Preceding unsigned comment added by ~2025-34127-94 (talk) 18:14, 16 November 2025 (UTC)

More work needed to exploit new sources

The article now seems a bit too concise. In the light(!) of the emerging richness of this topic, more details from the recently added modern sources could be added to the article to enrich it. Layzeeboi (talk) 21:09, 17 February 2017 (UTC)

How does it work?

"However, using quantum correlation between photons from the two beams, the correct image can also be recorded using complex light distributions. Also, the correct image can be recorded using only the single beam passing through a computer-controlled light modulator to a single-pixel detector." These two sentences don't really explain either process for the general public. And the term "correct image" has not been defined at this point.

Similarly, the first paragraph of the History section does not explain how it helps for the two photons to be entangled. Steve Wise (talk) 06:31, 27 September 2024 (UTC)
