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)[reply]

External links modified

Hello fellow Wikipedians,

I have just added archive links to one external link on Ghost imaging. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

Added archive https://web.archive.org/20080513050042/http://technology.newscientist.com/article/dn13825-quantum-camera-snaps-objects-it-cannot-see.html to http://technology.newscientist.com/article/dn13825-quantum-camera-snaps-objects-it-cannot-see.html

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

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)[reply]

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)[reply]
