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:
“This is the dead land
This is cactus land
Here the stone images
Are raised, here they receive
The supplication of a dead man’s hand
Under the twinkle of a fading star.”
—T.S. (Thomas Stearns)
“It seemed like this was one big Prozac nation, one big mess of malaise. Perhaps the next time half a million people gather for a protest march on the White House green it will not be for abortion rights or gay liberation, but because we’re all so bummed out.”
—Elizabeth Wurtzel, U.S. author. Prozac Nation: Young and Depressed in America, p. 298, Houghton Mifflin (1994)
