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:
“But psychoanalysis has taught that the dead—a dead parent, for example—can be more alive for us, more powerful, more scary, than the living. It is the question of ghosts.”
—Jacques Derrida (20th century)
“It may be the more
That no line of her writing have I,
Nor a thread of her hair,
No mark of her late time as dame in her dwelling, whereby
I may picture her there.”
—Thomas Hardy (1840–1928)
