...One extreme example is the single-pixel camera, which relies on a beautifully simple principle. Typical cameras use lots of pixels (tiny sensor elements) to capture a scene that is likely illuminated by a single light source. You can also do things the other way around, capturing information from many light sources with a single pixel... To do this you need a controlled light source, for example a simple data projector that illuminates the scene one spot at a time or with a series of different patterns. For each illumination spot or pattern, you then measure the amount of light reflected and add everything together to create the final image....

Some of these applications might require a little time to fully develop but we now know that the underlying physics should allow us to solve these and other problems through a clever combination of new technology and computational ingenuity.
I remember talking about this with a “spy” in 1988.
With my OM 2n, I could run around with a light and the shutter would close when it calculated the film was exposed.
In the dark, this could take a while.
This is just a bit faster.
I remember seeing those silly old ads :-)
Interesting article though...people would be shocked at the things being done with extremely high-frequency radar imaging.
These principle don’t just apply to the optical wavelengths.
- In 1998, Sony accidently sold 700,000 camcorders that had the technology to see through people’s clothes. The cameras had special lenses that use infrared light (IR) to see through some types of clothing. It primarily works on dark colored, thin clothing - like swimsuits. The main factor is how well the fabric ...

I remember those ads when I was a kid. Did anyone actually order them?
I think that in the near future (10-20 years) as display technology gets better, smaller, and cheaper, you will eventually have a TV room, where the entire room is literally the TV, the screen is integrated into the walls (and maybe even ceiling and floor) as sheets sort of like wallpaper. This would result in a sort of poor man’s holodeck which you would appear to be “in” the movie or TV show you are watching.
I think I heard TSA scanners produce such images? I recall seeing one which clearly showed the butt crack of people.
"...??..so she'll never know eh?"
I want a thermal camera in my phone.
LOL...You beat me to it! I’m still waiting for a pair that works.
BUT.... the high-frequency radar imaging can be turned into optical wavelengths.
That’s not seeing through walls.
Lol, was thinking same thing...
I didn't, but I did get to try out a pair. They wouldn't have kept putting the AD in the backs of magazines if no one ever bought any. And those ads were there for decades.
” I did get to try out a pair”
Well give us a review. How’d they work?
I want a thermal camera in my phone.
And that is why I originally clicked on this article.
Before retiring, we occasionally used a Flir camera($$$) at work.
I don’t NEED one, but I want one.
With two boilers in my house, pex in a slab and pipes that go who knows where in the 100 year-old house, I want one!
Chinese cheapies are about $100.
