sciencehabit writes: A mini-arms race is unfolding in the supposed field of quantum radar, spurred by press reports in 2016 that China had built one — potentially threatening the ability of stealthy military aircraft to hide from conventional radars. Governments around the world have tasked physicists to look into the idea. Whereas a conventional radar searches for objects by detecting pulse…

New Imaging System Creates Pictures By Measuring Time
An anonymous reader writes: Photos and videos are usually produced by capturing photons — the building blocks of light—with digital sensors. For instance, digital cameras consist of millions of pixels that form images by detecting the intensity and color of the light at every point of space. 3-D images can then be generated either by positioning two or more cameras around…
Watch a beam of light bounce off mirrors in ultra-slow motion
For the first time, researchers have taken a video of a pulse of laser light as it moves in three dimensions, using a camera with a shutter speed of a trillionth of a second. It could potentially be used to see around corners Source: https://www.newscientist.com/article/2249904-watch-a-beam-of-light-bounce-off-mirrors-in-ultra-slow-motion/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
