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:
“[He] didn’t dare to, because his father had a weak heart and habitually threatened to drop dead if anybody hurt his feelings. You may have noticed that people with weak hearts are the tyrants of English married life.”
—George Bernard Shaw (1856–1950)
“He said “Next time can I bring my friend?”
And I thought “Does he mean friend?”
And I thought “Yes he does mean friend.”
Which was quite bold in those days.
It was the Dark Ages. Men and men.
And they could still put you in prison for it.
And did, dear.”
—Alan Bennett (b. 1934)
