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 utmost familiarity with dead streams, or with the ocean, would not prepare a man for this peculiar navigation; and the most skillful boatman anywhere else would here be obliged to take out his boat and carry round a hundred times, still with great risk, as well as delay, where the practiced batteau-man poles up with comparative ease and safety.”
—Henry David Thoreau (1817–1862)
“Where have you gone? The tide is over you,
The turn of midnight water’s over you,
As Time is over you, and mystery,
And memory, the flood that does not flow.”
—Kenneth Slessor (1901–1971)
