https://hackaday.com/2019/08/22/looking-around-corners-with-f-k-migration/
The concept behind non-line-of-sight (NLOS) imaging seems fairly easy to grasp: a laser bounces photons off a surface that illuminate objects that are within in sight of that surface, but not of the imaging equipment. The photons that are then reflected or refracted by the hidden object make their way …read more (https://hackaday.com/2019/08/22/looking-around-corners-with-f-k-migration/)
