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:
“If the dead talk to you, you are a spiritualist; if God talks to you, you are a schizophrenic.”
—Thomas Szasz (b. 1920)
“The vines of her arms
didn’t cling to the ends of his clothes,
or did she plant herself in the doorway,
hurl herself at his feet,
or utter the word “Stay!”
But as that fool began to go
at the time when it was dark with swarming clouds,
the slim girl blocked her lover’s way
with only a rising river
made with her flood of tears.”
—Amaru (c. seventh century A.D.)
