“But researchers at the Stanford Computational Imaging Lab have expanded on a technique called non-line-of-sight imaging so that just a single point of laser light entering a room can be used to see what physical objects might be inside.”
The image is a blur and it only works if something in the room moves. A mannequin comes out looking like a ghost. The friendly pitch is self-driving cars. The other use named is police and the military, checking a room through a crack before they kick the door in. Guess which customer pays first.
