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 way in which men cling to old institutions after the life has departed out of them, and out of themselves, reminds me of those monkeys which cling by their tails—aye, whose tails contract about the limbs, even the dead limbs, of the forest, and they hang suspended beyond the hunter’s reach long after they are dead. It is of no use to argue with such men. They have not an apprehensive intellect, but merely, as it were a prehensile tail.”
—Henry David Thoreau (1817–1862)
“The militancy of men, through all the centuries, has drenched the world with blood, and for these deeds of horror and destruction men have been rewarded with monuments, with great songs and epics. The militancy of women has harmed no human life save the lives of those who fought the battle of righteousness. Time alone will reveal what reward will be allotted to women.”
—Emmeline Pankhurst (1858–1928)
