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:
“O women, kneeling by your altar-rails long hence,
When songs I wove for my beloved hide the prayer,
And smoke from this dead heart drifts through the violet air
And covers away the smoke of myrrh and frankincense;
Bend down and pray for all that sin I wove in song....”
—William Butler Yeats (1865–1939)
“As the farmer casts into the ground the finest ears of his grain, the time will come when we too shall hold nothing back, but shall eagerly convert more than we now possess into means and powers, when we shall be willing to sow the sun and the moon for seeds.”
—Ralph Waldo Emerson (1803–1882)
