For detection systems that record discrete events, such as particle and nuclear detectors, the dead time is the time after each event during which the system is not able to record another event. An everyday life example of this is what happens when someone takes a photo using a flash - another picture cannot be taken immediately afterward because the flash needs a few seconds to recharge. In addition to lowering the detection efficiency, dead times can have other effects, such as creating possible exploits in quantum cryptography.

Famous quotes containing the words dead and/or time:
“Alas, how quickly the gratitude owed to the dead flows off, how quick to be proved a deceiver.”
—Sophocles (497–406/5 B.C.)
“I take enormous pleasure every time I see something that I’ve done that cannot be wiped out. In some way ... I guess it’s a protest against mortality. But it’s been so much fun! It’s the curiosity that drives me. It’s making a difference in the world that prevents me from ever giving up.”
—Deborah Meier (b. 1931)
