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:
“There had been a time on earth when poets had been young and dead and famous—and were men. But now the poet as the tragic child of grandeur and destiny had changed. The child of genius was a woman, now, and the man was gone.”
—Thomas Wolfe (1900–1938)
“The greatest waste of time he knew of was to count the hours—what good can come of it?—and the greatest illusion in the world, to lead one’s day by the sound of the clock, and not by precepts of common sense and understanding.”
—François Rabelais (1494–1553)
