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:
“With this pen I take in hand my selves
and with these dead disciples I will grapple.
Though rain curses the window
let the poem be made.”
—Anne Sexton (1928–1974)
“Our deeds disguise us. People need endless time to try on their deeds, until each knows the proper deeds for him to do. But every day, every hour, rushes by. There is no time.”
