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:
“Swimmer of noonday, lean for the perfect dive
To the dead Mother’s face, whose subtile down
You had not seen take amber light alive.”
—Allen Tate (1899–1979)
“I have heard of a minister, who had been a fisherman, being settled in Bridgewater for as long a time as he could tell a cod from a haddock. Generous as it seems, this condition would empty most country pulpits forthwith, for it is long since the fishers of men were fishermen.”
—Henry David Thoreau (1817–1862)
