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:
“I see that every man that went in had his pockets bulging, or something muffled up under his coat—and I see it warn’t no perfumery either, not by a long sight. I smelt sickly eggs by the barrel, and rotten cabbages, and such things; and if I know the signs of a dead cat being around, and I bet I do, there was sixty-four of them went in. I shoved in there for a minute, but it was too various for me, I couldn’t stand it.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“It’s true, as Marya Mannes says: “No one believes [a woman’s] time to be sacred. A man at his desk in a room with a closed door is a man at work. A woman at a desk in any room is available.””
—Lillian Breslow Rubin (20th century)
