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:
“And what the dead had no speech for, when living,
They can tell you, being dead: the communication
Of the dead is tongued with fire beyond the language of the living.”
—T.S. (Thomas Stearns)
“Today is made of yesterday, each time I steal
toward rites I do not know, waiting for the lost
ingredient, as if salt or money or even lust
would keep us calm and prove us whole at last.”
—Anne Sexton (1928–1974)
