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:
“You common cry of curs, whose breath I hate
As reek a’th’rotten fens, whose loves I prize
As the dead carcasses of unburied men
That do corrupt my air—I banish you!”
—William Shakespeare (1564–1616)
“In the middle of the night, as indeed each time that we lay on the shore of a lake, we heard the voice of the loon, loud and distinct, from far over the lake. It is a very wild sound, quite in keeping with the place and the circumstances of the traveler, and very unlike the voice of a bird. I could lie awake for hours listening to it, it is so thrilling.”
—Henry David Thoreau (1817–1862)
