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:
“The sea cries with its meaningless voice,
Treating alike its dead and its living,”
—Ted Hughes (b. 1930)
“I cannot exaggerate the waste of the President’s time and the consumption of his nervous vitality involved in listening to congressmen’s intercession as to local appointments. Why should the President have to have his time taken up in a discussion over ... who shall be the postmistress of Devil’s Lake, in North Dakota? How should he be able to know ... who is best fitted to fill such a place?”
—William Howard Taft (1857–1930)
