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:
“So, when old hopes that earth was bettering slowly
Were dead and damned, there sounded ‘War is done!’
One morrow. Said the bereft, and meek, and lowly,
‘Will men some day be given to grace? yea, wholly,
And in good sooth, as our dreams used to run?’”
—Thomas Hardy (1840–1928)
“And the unfailing sense of being young
Spread out like a spring-woken tree, wherein
That hidden freshness sung,
That certainty of time laid up in store....”
—Philip Larkin (1922–1986)
