How An Ordinary Camera Phone Can Photograph Objects Hidden Behind Other Things — The Physics arXiv Blog — Medium

How An Ordinary Camera Phone Can Photograph Objects Hidden Behind Other Things — The Physics arXiv Blog — Medium: The trick here is to treat the data from each pixel as a separate image. The task then is to look for the correlation between each of these images, just as in the single-pixel imaging techniques...

And they even produce images using reflected light (as opposed to transmitting light). To prove this, these guys recorded the light from an object that was scattered off a wall covered in white paint.

Sure enough, the resulting image revealed the object, even though it was essentially around a corner from the camera.
