current event on cameras

1. I learned that cameras can look around corners and a laser pulse is fired .Hits the wall and scatters  some photons reach the camera at different times .This is no ordinary camera it has a time  resolution of 2 pico seconds. That's how long it takes light to travel 0.6 millimeters and that distance travels with sub mm precision . they have cameras that can see around corners in 3d .The camera was developed at a university called Edinburgh    includes an array of photon sensitive pixels each of which can capture single photons and be activated for just 67 pico seconds, about a billion times   faster than a human blink. thees are two different cameras that can do things thats amazing
