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:
“They have given us into the hand of new unhappy lords,
Lords without anger and honour, who dare not carry their swords.
They fight by shuffling papers; they have bright dead alien eyes;
They look at our labour and laughter as a tired man looks at flies.”
—Gilbert Keith Chesterton (1874–1936)
“I waited alone, in the company of orchids, roses and violets who—like people waiting beside you, but to whom you are unknown—maintained a silence which their individuality of living things rendered more imposing and in their chilly manner received the heat from an incandescent coal fire, preciously placed behind a crystal glass, in a white marble tub where it dropped, from time to time, its dangerous rubies.”
—Marcel Proust (1871–1922)
